Loneliness causes addiction

I have some friends but i just don't like that definition. Is like we are talking like a guy that like to stay alone like a guy that pass his time on is room and don't do anything outside masturbate, videogames, ecc...
I feel comfortable, with people with my same interest, well, there is not many, so i will stay alone, there is a lot to study. I go to the gym, without having friends, videogames started to boring me, tv series and movie mostly annoying me, i go run and i have do a 72km mountain marathon and i was alone, i can do everything a social guy do, but if i see only organic portals/hylics that think only to sex, party, and annoying things (for me!), about these people if you have learned, some time is better to stay away, because are mostly Energy-drainers people and i don't want to feel bad....this is just my experience and my definition, but i said before that not everyone can feel confortable in loneliness so i understand you if you hate it.
