Question about LGBT student center/club thingies at colleges

I'm currently discovering a lot about myself, and it's been a rough ride at times. I'm still pretty new to this, so I was kicking around the idea of stopping by the LGBT student center on my campus to see if I could meet people. Not romantically or anything, at least not right away. I'm in no hurry. I'm just looking to make some friends. Loneliness has really been screwing me up lately, and I think I need to do something about it before I become a total basket case.I'm a bit old for a college student (mid 20's), and I'm not really sure I'd fit in there. I'm bi, favoring towards gay, but for the most part I appear pretty straight. So much so that I'm a little worried they would think I'm just yanking their chain or something. I have only mediocre people skills, so I might not always give the best first impressions.I'm just afraid of going there and being rejected. I'm pretty sure I won't fit in well, and the self esteem hit of being shunned isn't something I'm too eager to subject myself to right now. Plus I get the impression that dudes like me wouldn't be going to places like these very often, and they might not even know what to do with me.So yeah, I guess I'm just wondering if anyone was helped by these kinds of places and what kinds of things they usually do. I know they exist, I just don't know who or what they're specifically for. If they're meant for people that have real problems, then I don't want to waste their time. I just don't have any idea what to expect.Thanks in advance for any insight you can share. I truly appreciate it.
