Baruch, I am late here in the sense that you are already gone to sleep so you won't be reading this now. It's nothing important, I just wanted to add one thing about the meeting you will have with the psychologist in a few hours.
If you don't want to tell him about your suicide thoughts because he will have to tell your parents, without lying you can just rephrase it in a way so that he won't have to report it.
You might say that your life is so miserable at the moment, that everything seems meaningless. It's just an example, but there are ways to convey your feelings of utter desperation without actually SAYING the word "suicide".
I wish we had psychologists in school when I was a student, it's a great opportunity you have to speak with someone who can give you a lot of help in understanding yourself a little bit more and quicker. And as others have already said, he can be an excellent mediator. He might be the right person to speak to your mother and make her see the bigger picture. She wants you to be happy, she just needs to understand what happiness means for you. This guy can help on this, I am sure. Use him as much as you can!
Don't think in terms of failure, please. Your school's program is brutal! Success in life is not measured in school results anyway.
I was a bad student, lots of problems with authority, not interested in most of the subjects etc. etc. nevertheless a few years later I had a great career with a job I adored. Millions of other people can tell you this same tale.
And one more thing, the most important of all, of course: you must think of MY happiness!
I always look forward to read your posts and your new crazy breeding plans, you are a very interesting person and I enjoy living on this planet knowing that you are around, and probably one day you will create The Green Tiel! Sorry but you'll have to stay
