Hi Squig,
Welcome to Psych Central!

I really don't know the answers to your questions. I understand you to be saying at times you behave inappropriately. Other times you might want to behave inappropriately but you are able to control yourself. It sounds like you do need to find someone to talk to. High School can be a very stressful time and feeling unsure about yourself is very common. I hope you will talk to a teacher who seems sensitive or a guidance counselor and see if they can provide some direction. Perhaps one of the teachers who referred you for social training.
Meantime, feel free to come back here for support and share what's going on with you. I have found the people here very supportive.
