Hi, Baby-Face!
Actually, anger management classes or counseling sessions, especially if they might involve others who also are around the same age as you, might be a good thing! You could learn a lot about yourself, how to cope so that you feel better about the things that you do, and also maybe make some new friends who have similar issues with which to deal in their own lives.
Concerning your crying, well you know that you are growing and changing in a lot of different ways. Growing and changing in a lot of different ways can also affect a persons emotions a lot!
If you would like to continue to post about how you think, act and feel, then please do! There are many people on this site who would be willing to give you "a shoulder on which to lean" and also positive and proactive feedback which would be helpful to you.
We care about you here!

This is also one of the safest sites on which you could participate and talk about the frustrations that you have!
Thanks!
