I'm sorry you are going through this. College applications can be quite invasive at times but they can also use the information to help you if you do get in. They generally want to know that you are doing ok now. Although the questions are a bit tricky in this case as they generally would relate to behavioural suspensions and not mental health concerns.

It seems you have done all of the right things in trying to talk to people so I really encourage you to keep trying to contact your T and the admissions office. They can guide you through it and help you with the application so that you say what you need to but it doesn't give away personal information that they really don't need to know.
