Hi and welcome.
You need to get out and do something that interests you and makes you feel more proud of yourself.
Think of things you admire or sports you think are cool. Then go out and try and find a club to join, there are many lonely people who join clubs just to get some social interaction.
Try going out to a bar or club, even on your own, there are many loners out there who cruise bars on their own, I sometimes do it.
Your isolation will drive you crazy if you don't do something about it.
You may even have some fun.
