Tierd of being shy.

You don't talk much, but you want to get closer to others.

You can't get closer with others or expect them to open up to you if you're backing away and closing yourself off from them.

It's not enough to just be around them or work with them. It's not even enough to just talk to them. You can do all these things while still not opening yourself up to them or letting them get to know you. You can be around somebody for a long time without ever getting to know them because they keep themselves hidden or private.

You say that you don't have anything to talk about, but what you're really saying is that you don't want to share anything about yourself. You don't want to bring down your emotional guards. You don't want to let yourself be seen by others.

This is basically what you're doing =
You - Hi.
Them - Hello.
You - How's it going?
Them - Good. You?
Them - I'm alright.

..................... That's talking and making an effort, but you shared nothing about yourself there. You didn't add any value to the conversation. You didn't talk about anything they're interested in or anything that you're interested in. You didn't share what's going on in your life or about who you really are. You didn't give a compliment. No humor. No genuinely curious questions about them. Nothing. You basically interrupted them and expected them to open up and do all the work without you having to risk any sort of real vulnerability.

They don't know you because you don't show them who you are. You most likely don't stand out. You don't do or say anything around them that would draw attention towards you. That's the problem. You live a very safe life. You have very safe conversations. You protect yourself from the dangers of socializing with others. You're overly concerned about keeping yourself out of danger / mistakes / rejection / failure. You behave in a safe way and you'll have safe results. You have nothing to say? Well then others have nothing to hear. You have nothing to share? Then why would other people be interested?

During class you can slam your hand really hard on the table and that would be better than anything you've done so far in terms of getting people interested in you. Because it's taking a risk and allowing yourself to be seen. Because it's sharing more than anything you've done so far. You and the others will actually have something real to talk about ("why did you slam your hand on the table and interrupted the class like that?"). That's more vulnerability than anything you've done so far.

The other people that bonded with each other allowed themselves to be seen. They let their guards down. Shared themselves with others. Allowed others to get to know them. They risked rejection or making mistakes.

You say that you're tired of being shy, but other people are also tired of you being shy. People don't like interacting with someone that seems like they have a hidden agenda that they aren't sharing. Too secretive, boring, and safe. It drains the energy of others.

 

Same thing.

You don't want to say or do the wrong thing. You become very cautious. You play it safe. You don't win, but you also don't really lose. You fear rejection and avoid it. So you do and say very little. You hide yourself. You keep things to yourself. So she won't accept you, but she also won't reject you. You take no risks and show no vulnerability.

When you say you don't know what to say to a girl you're interested in... what you really mean is you can't think of the perfect thing to say or do that will lead to the perfect outcome that you desire. You want a guaranteed method to attain a guaranteed result. You want absolute control. You want zero chances of pain / problems / negative experiences. That's not reality. You resist reality and that's what causes your anxiety and hesitation. It's not that you don't have anything to say to her. It's that you don't want to say what you really want to say.

When I find someone I'm interested in, I don't play games. I don't play it smooth. I don't act like I'm not interested. I don't slowly build her trust and slowly bond with her before making a big reveal about my feelings. I tell her right away what I like about her. No secrets or hidden agenda. She knows what I like about her and what I want. Even if she doesn't have mutual interest, she will respect me more for having the self respect of going for what I want and taking risks.

 

For most people shyness is caused by overly heightened awareness and 'fear' of others thinking negative/bad stuff about oneself. Quite often, shy people are people-pleaser and doormats, in a sense that they have a hard time saying "no" to people because of a fear that people will either leave/drop them or have a negative opinion about them.
The root cause of this problem is a lack of "self-respect". If your own opinion about yourself is not more important than a stranger's opinion about yourself then you are not respecting yourself, not at all.
The single most important thing is not to be liked by others, or being popular and respect by others. The single most important thing is to "respect yourself". Nothing more, nothing less. If you start respecting yourself, or even take things further and start 'liking' yourself, or god forbid, even 'loving' yourself. Then other's people reactions and thought's about yourself won't matter as much.
And because you then know and own who you are that you don't feel 'risk' in 'expressing' who you are. It's when people stop being shy.
Newbies have a hard time at this and quite often 'overcompensate' their lack of self-love and self-respect with fake-confidence. this comes often off as arrogant and narcissistic. Take care to not overcompensate.
It's true that your own opinion about yourself and your life outweighs any else opinion but that doesn't mean you get to disregard other people and their opinions all together. If it is something not pertaining your core-personality or core-related issues, like your dreams, goals etc... then your opinion isn't worth more or less than those of others.
