Reading this is like going back in time for me.. I can relate to almost everything that you said.. Well, apart from the fact that I'm a lesbian woman.. lol..
I am so sorry you're in such a difficult place right now, and I really wish I was there to give you several hugs. I'll give you this virtual one though....
I'm not sure where to start, but I wish it would be easier for you to be yourself... Coming from a tiny place myself - and from religious parents - I can relate to the fear of anyone knowing. It's horrible.. And it is tiring.. But there is a way out of it. It might take a while but it's there. Please remember that. And also please try to think in the middle of it all, that you are ok. You are great the way you are, and you have nothing to be ashamed of.
Is there any way you could move out for a while? Share a flat with someone? I'm thinking that it might be easier for you if you're a bit further away from your family.
I was online for quite a while talking to people on various forums before I told someone in real life, so I can relate to that too.. What you could try though is someone professional, like your doctor or some health staff at the college perhaps?
I'd also recommend trying to find some gay student groups. If you tell them that you want to be anonymous I'm sure they'd respect that. I can understand that it's scary, though.. I would think you could meet someone from there in a "safe" area like a cafe or something. No one would know if you're just sitting there having a cup of coffee, right? I did that once myself, and the guy I met was very nice. :) I also remember the first time I went to a gay bar - I went around the block for an hour before I went in.. I finally did though, and it wasn't as scary as I thought it would be.
You don't know how your family and friends will react before you tell them. But I understand that it can be scary, and I also would recommend that you have some support around you when you do. Because it can be really hard if they react negatively. I waited for a while before I told my family, and I'm glad I did. Though it wasn't easy to wait either.. It's a decision you will have to make though. When to tell people and if you feel ready for it... I must tell you though, that it felt like a relief when I finally told someone. It's so much better not having to hide it all the time.
It can get better, and you can be happy with who you are. I'm now living with another woman, we have an apartment and my family invites us home for Christmas...
You're not alone and you can get through this.
Many hugs from me.
