@Dalmaty No worries.

I really really wish I had thought to ask for help and support when I was a teen. It's easy to feel lost, and overwhelmed, especially when it is easy for adults to say "ah, that is just you being teenage!". Plenty of adults have some of the same problems you are having, they are the problems of being human. This does not make them easy to deal with, but getting good support now will hopefully give you tools to deal with the same problems when you are older.

You are mighty.
