I've always felt inferior, and boring, and it's taken a lot of work for me to even be comfortable in my own skin, I'm a couple years older than you, never been in a relationship either, and also felt that most of my friends had grown to hate me and I isolated my self from them, and too eventually burning almost every bridge in my life, and seriously damaging a couple of the ones that still stand. The isolation only made things worse, it made making new friends harder after spending weeks completely isolated, and eventually just becoming completely disinterested in any socialization, I wouldn't even leave reddit comments because "Who really fucking cares anyways". So why would I even bother with trying to make a new friend? Or a girlfriend?

​

Well I eventually came to the idea that I was the common denominator in all of this , so I started seriously working at improving my self. Slowly, but making improvements, I really did have to learn to love my self before I could even begin to consider being able to fully love someone else. I still don't feel that I can and I'm a year into my "recovery". Try not to focus on dating man, it really isn't that big of deal if you get your dick wet or not . Look for a new hobby, get into meditation and yoga, go to therapy if you really feel you need it. Hone in the skills you already have, and try your best to be the best you at all times. Anything but isolating your self, because god damn it man I wouldn't wish this sort of life on anyone, after five years trapped in my home I changed, and I haven't been the same. I get so worn out from any interaction with other humans anymore, but I don't want you a couple years from now regretting your decisions like I have. Good luck man
