Hello and welcome to the forum! I have a few random thoughts, which may or may not be helpful:

1) Don't give up on the girl. Take it very slowly and work toward establishing friendship. Then, perhaps, something romantic will happen. You never know.

2) Write down the things you want to discuss with your therapist; that way, you won't forget them.

3) As for being "pissed off" during a manic episode, I am frequently very angry when manic or mixed, but never when depressed. (Although anger sometimes triggers depression.) It's taken some time to realize this and watch out for it so that I can stop myself from doing destructive things.

Take care.
