The teens and early twenties are perhaps the most stressful, anxious times in life. It's amazing how many problems go away by themselves within a few years.
If you're being harassed, don't worry about it. By the time you're in college or the workplace, it stops. Other people eventually mature and have other things on their minds--they're really not much interested in picking on other people.
In general, things get better as you get older. Even if all the problems don't go away, they feel much less overwhelming. You develop patience and even a sense of humor. You can say, "Is life absurd? Very well, life is absurd--maybe it's supposed to be that way." And then you can deal with it on those terms.
The real problem is that we like to believe life runs smoothly. Then, if something goes wrong, we get upset. In other words, it isn't life's difficulties that upset us so much--it's that our world view of "everything is supposed to be fine" get's shaken, and that's what upsets us.
About this the Buddha said "Life is very difficult. Once you understand that, life becomes easier."
Maybe you don't know if you are a boy or a girl--or which path to take. And this makes you anxious.
Okay. Who says that you're supposed to know? The anxiety comes not from the confusion, but because you think you're supposed to have an answer. Accept that you don't have an answer. Maybe you won't have one for a while. That's okay.
Suicide
A statistical law of the universe is that things move toward the average. That means if things are really bad, they will tend to get better by themselves.
There's no point doing something desperate like suicide. Suicide is a permanent solution to a temporary problem. Think about that.
You are important.
You were put on this earth for some very important reason. You probably don't know now what that reason is--in fact, you might never know. But you can be sure that there is a reason. Other people need you--they need your concern; they need your support; they need your help.
Understanding that is a big key to life. As long as we dwell on our own problems, we're never happy. The reason is because as a social species, human beings are designed to help each other.
To paraphrase John F. Kennedy's words, "Ask not what others can do for you; ask what you can do for others." Once you realize that, a huge and impossible burden is lifted from you-- that of worrying about yourself!
Nobody can see their own life objectively. However, we're really pretty good at sensing another person's problems; and can truly help them, because we're objective about their problems.
Don't believe everything other people say
Black-and-white thinking is a big problem. These days it seems like there are two extreme views about transgenderism. Religious fundamentalists say 'queer' is completely bad, whereas most transsexuals and crossdressers say it's completely good.
Most people have the sense to dismiss the first view, but, unfortunately, few see the shallowness of the second view. The view that "if it feels good, do it" has itself become a religion.
The truth is that "moderation in all things" and "finding the middle path" are still good ways to go. There's no need to be all one thing--all male or all female; all hetero or all gay. It's a mistake to think like that.
