Who cares what you're into. Don't think that your interests are the cause of all the problems. I also do cosplay. Only a little different in that I do not cosplay on anime but on characters from various games. Recently I bought myself
purple eye contacts and various wigs to cosplay on Dota 2. I'm a gamer. And also spend all my life in my laptop. But that doesn't stop me from making friends online. In those very games. It's just important that there would be a desire. Take care of yourself and find people with common interests. At least you won't be so lonely.
