I need to talk with someone about this, Its just getting to much, so many problems, Im only 17?

Hey I am a 17 year old guy.When I was younger, I remember liking girls and wanting to be with them. I always wanted to have a traditional family with 2 or 3 kids and a wife. But when I went into secondary school, this all changed I started liking guys (ually). As my first year went by I started really liking this guy (both ually and emotionally) He was affectionate,funny, cool, friendly, one of the nicest guys I had ever met, and not to mention extremly good looking. I was always shy, and he would be the first always to talk to me, and be friendly with me, he always gave this amazing smile. he was the nicest person ive ever met. Well as the first year and soon the second year went by, I began to love this guy, he was something really special, I felt something with his presence that ive just never felt with another person before. From these feelings I had from this guy, I really then realised I was gay. I felt that I couldnt tell anyone including him,because in school I would of been afraid of being bullied hurt etc, not even my friends, I just didnt know how they’d react. I couldnt tell my parents either as for the same reason as my friends, they seem to be anti gay (religious opinions :( ) well as my third year in school went by, my love for this guy just grew and grew and I knew that this wasnt a crush this was completely true love. Well I finished my third year, and came back for my 4th year, to find this guy had left my school and had gone :(, My heart was completely broken and still is. I tried my best to track him down but I cant, noone knows where he is. I am devistated about this, I dont know what to do, I feel so sad and depressed, and the worst thing is that I cannot tell anyone how I feel because I am afraid. I lost a great friend and a true love, all I want is him, I love him so much. Ive tried everything I can think of to contact him, but I just cant get through to him, noone knows where he is. I sometimes get these dreams about him ( i cant remember them all exactly) but all I remember is his smile, and the feeling I got when He smiled at me. I feel I need to talk with someone about this, but who ?. Last year I was sick and out of school for 2 months (swine flu and sever fatigue (Circadian Rhythm problem)), when I went back to school, everyone had changed, and all my friends just werent friendly anymore. I feel I have noone, No friends, and I feel so lonely. Ive tried talking to them, but its just not there, what we used to have. My family wouldnt be supportive of me being gay. They are anti gay ( beleive that its wrong to be gay and that gay people is the work of the devil and end of human creation, its weird, I dunno where they got this stuff from), so I cant talk to them about it. I have noone but the internet. Its terrible, I feel stuck and alone. I just need to talk about it and see if other people have had similar problems.And what can I do to feel better??? I feel just so trapped and depressed, I dont know how to explain.
