I wonder if the damage is too much. Is it over for me?

Actually you are alone mate, in the sense that you alone have to make the decision. Just stop looking orn and masturbting.
That simple. You did enough damage to yourself, wake up!

 

No offense, but I just skimmed through your story and didn't read everything. Same old, same old. Tell me again: what about your situation is any different from ours? This is such a generic story. Take this as encouragement.
You have a problem that many others had had and overcame. There is a fix, you know it. You already know what to do.

 

The title of your post 'is the damage too much is it over for me' represents a defeatest attitude and i've heard it a lot and been through it myself. Often people with addictions will tell themselves these things as another reason to stay in the addiction, ie: 'i'm an alcoholic so i have to drink' sometimes it is difficult to find the strength or courage to overcome those demons and for some people like myself I had to reach rock bottom before i was genuinely desperate enough to seek proper help. My porn problem was made a lot worse through the use of narcotics but finding help for my drug use really helped me with porn too, I also got professional psychotherapy but importantly I was ready and willing to do anything to beat the addiction. I'm over 3 years sober from everything now and I was in a very bad way so if i can overcome it so can you! you just need the right level of support and the right mindset and to take each day at a time, try not to think too far ahead like 'am i ever going to get another girlfriend' etc or ruminate over your past mistakes.

It's all about progress not perfection so start to think about things you can do in your day to day life that will improve your positive thinking, things like taking better care of yourself, watching motivational videos, making small achievable goals and meeting them, finding someone to talk to etc all helps to get you in a good mindset.
