Moving on and accepting

Hi (I'd like to thank people for their help in advance, I'm very grateful to you for listening).

My problem is an odd one and I'm mostly sharing my problem because I feel an emotional need to; hopefully I can explain fully.

I've been living with three guys for the past two years while in college. When we first started living together it was okay; we all seemed to get along and they seemed nice. I even counted them as friends. Slowly, one by one they started to be nasty and make snide comments. All of these comments were masked with hints of sarcasm and humour, but it was never very clear if they were being serious or not.

Then, particularly in the second year, comments got nastier and less of an effort was made to laugh them off as jokes. A few times they would shout at me or get angry at me for nothing. Once, I acted surprised at one of their favourite films and the person shouted at me and told me to stop talking to them, they wouldn't even look me in the face and I apologised several times for upsetting them. One of them in particular, made fun of me all the time. He would pick up on every little thing that I did or said or ate or wore.

For awhile now, its gotten so bad that all I do is stay in my room. When I enter the public areas in the house (kitchen or sitting room) I can't help but breath a sigh of relief when I find that they're not there.

They exclude me and they've made me cry on several occasion, but I've done that less and less. One time, encouraged by my boyfriend to do so, I confronted them and was very upset. Things were better for a short while, but they never actually said "sorry".

They've made the last two years of my college life complete hell. They've emotional broken me down and destroyed my confidence. I've confided in my boyfriend, sister and a few of my friends how I feel. They've told me, these people have low self-esteem, It's not me, I've been told these guys fancy me, etc as a way of explaining the treatment.

I've looked in on myself and tried to think what I could do to stop it or to see if it was my fault in some way. But to be completely honest, I've never had a problem like this before, usually people get on with me, I like a laugh, I never complain about the house being dirty (which it always is), I'm nice and patient with everyone. I really don't think its something I'm doing.

I try and put it out of my head, and college is nearing an end so I don't think I can change anything now. But, I need help getting over the emotional abuse (its the only way I can describe it) that I've suffered for the last two years. I have no confidence and I'm crippled by the whole ordeal. It's all I can think about.

I would love if someone could give me advice on why they think this happened and how I can move on and forget it and start building my confidence?

Thanks so much
