It's been about 5-6 years for me since my ex broke up with me, I haven't dated much since. She creeps into my dreams and makes them nightmares, even on days when I never had my mind on her. She was someone I thought I would spend the rest of my life with, but it wasn't in the cards, and that's OK. You need to show yourself some tough love, and suck it up. It's a bit heartless, but sulking about it makes things that much more difficult for you.

Use her as a stepping stone towards your new self. Cut off the parts about you that weighed your relationship down. Start slow, take each day at a time, focus on your job, maybe stay a few hours of overtime, keep your mind occupied. Maybe talk with your parents/family or friends, get some insight on how they dealt with heart ache, you're definitely not alone when it comes to this type of thing. Just don't expect miracles, or put yourself in a false sense of hope, be realistic about your goals/expectations.

Chin up, chest out.

 

buy a journal and hand write out some stuff. I know we have computers and this is a good forum, sometimes perfect solace can bring out some creativity and maybe that eureka moment will hit you? Just a thought. I feel you from the stand point of investing time, my mind and soul to something that should have been but ended up not being. The anger and all that about someone else in their life, but just work on improving you and dont fall for the pmo trap and just keep being more and more self resilient.

 

Teaching yourself to read a book or write a journal will be 100x more helpful than any digital device.

Understand your subconscious brain will be the first step to realising the triggers to the behaviour you're struggling with

 

great advice man, i learned a lot from your post. Thank you

 

On those days, you gotta call up a friend, and get out of the house. Take a nap is another option

 

Make some imaginary friends to help you snap back to the real world when you start thinking about her. That's what I did and it was one of the best things I have ever done.

 

You've gotta leave your comfort zone and do something that will make you feel better and productive. Whenever I feel rejected or depressed, I usually read a book or do as many push-ups I can in a row and already feel good about myself. Don't listen to sad music that reminds you of your ex, this just makes everything worse.
Remember that all this internal and external discomfort/pain is temporary. Get back up and achieve something man, you got this.
