I think you did a good job of expressing yourself.

If you have a psychologist you might tell him a few of the things you want to, and see how he reacts. If you trust him from that, then you might tell him a few more things.

In school, you do not necessarily have to put on a tremendously happy face. You don't have to tell other people any more about yourself than you want to. Leave that to people you trust, if any -- and to us here, as you get to trust this place.
