Everyone is different but based on my experience you should try to fill your days with new hobbies. If you can, invest money into it. Learn new skills. Do things you never thought about before. Have strong opinions. And most importantly be proud of yourself for all of that. You will hopefully start to like yourself and like being by yourself.

I never stopped feeling like an outcast but I did stop being sad about it. I don’t fit the norm but that can be a good thing.
