Need some help. How do I improve my social life? In college I am not the quiet guy and usually always with someone in breaks etc., or find people but it doesnt feel like I have friends because neither do I have a group nor have I gone out with college people at all. Only interactions with them are in college.

I stuck around with a couple of people but it doesnt seem they value me and dont really call me/approach me - it's mostly just me finding where they are and sticking with them. I usually try to have a good time with people and talk to them but I am having a terrible time making friends.  I cant seem to make any.  I am mostly the one approaching people and messaging them. 

People have already formed groups in my college and most people in my college have friends so if sucks not being one of them. 

When I find a group I chat etc., and when it gets boring I leave. Greet mostly everyone I know. I am unable to figure out what's wrong with me and this has been taking atoll on my studying aswell since I think about this issue so much.
