A gay teenager to become upset and sad when seeing a hetero couple?

I was the same way when I was in high school. It got a little better after that. I enlisted in the services, and surprisingly there are a lot of gay people (according to only 2 that I know personally). I'm trying to get that gaydar thing so I can pick them out and make friends. It's not where I want it to be, but it it's slightly better. It will get better for you too.

Get used to it. Being straight is the most normal, common thing, so......

youre lame!
the last thing you should
ever do is take your own life.
its like if everyone was gay and
i was the only straight person
in my school. i wouldnt consider to kill
myself. move schools,meet people.
youre just as lame as the girls who complaint
they dont have a boyfriend.
LAME !!!!!!!!!!

That's completely normal. You're emotionally ready to start an intimate relationship with someone, and have no one to choose.
Your home life doesn't provide the options you need, but that doesn't mean you should commit suicide.
You remind me of someone I used to know. I moved to a small town (500 population) in ND when I was 13, and a friend of mine had a gay older brother, (who was extremely smart and helpful with my dreadful homework ;_;) He was lonely, and eventually had boyfriends about an hour's drive away. Before I moved out of ND I found out he was going to college in another state, and no one had to tell me he was happier. He played the cards he was dealt with, and chose his own life the moment the opportunity rose.
I know there are times when you look around and feel like fate is laughing at you, but just remember that you have your WHOLE life ahead of you. Try making friends online, that's a start. It sucks having awesome friends living far away, but it makes life easier to deal with.

I'm straight and that happens to me when I see gay couples, Lol. Like, "Dang, even THEY can find someone they like despite the fact that they are a minority!"

Don't commit suicide, honey. One day you'll meet someone who makes every totally worth it. Just give it time, I promice someone will come your way, and you'll be glad you wated so long for them:)

Im going through the same thing in school as well. Though Im bi. I think about sucide. ITz normal...get on with your life...there's plenty of fish in the sea

I was exactly the same way in school: I thought I was alone and was made pretty depressed that the only affection ever shown anywhere in life, tv or history books was hetro. I even had a few suicidal thoughts as a teen. Eventually it becomes less annoying. The fact that much of mainstream society tries to pretend we do not exist also becomes less annoying when you eventually meet other gay people and realize we do exist in great numbers. Even the history books handed out in schools are edited to hide the existence of gay people (ancient Greece was an extremely gay society). And when you eventually notice that everything you see on TV, in the mall and in church is a lie, these things bother you less and eventually make you laugh.
In my case, I ended up moving to Holland where gay people do show up in everyday life, on commercials, are publicly married and even run for president (prime minster). When you get out of school and if you find your city is too backwards, you may wish to think about moving to a more sophisticated city in the US or elsewhere.
