Have you tried having a serious discussion with the school psychologist? They should be able to talk to you on a professional level without letting the friendship cloud their judgement. It is normal for parents to want to know everything and they do it because they love you and worry about you. My parents are the same. It might be nice for you and them if you started to learn to trust them by talking to them. Go at your own pace, talk about minor stuff to start with and build it up. Hopefully, by then, you will have 2 more people you can talk to. As for your plans after High School, you can achieve whatever you want to. All you have to do is believe and do your best.
