Hey there. I recently was in somewhat of a similar situation to you. I was also at school and my T + psych were through the school. When I went on medical leave FOR DEPRESSION, my care was terminated.

So I really do understand your frustration and fears. Have you talked to the therapist about possible options? Do you have insurance? If so please consider getting a therapist outside of the school. (I realize insurance is often through parents - I was also worried about this... if you are worried I think it's better to get the help you need in this case. Make up stories if you have to or be vague but it's so important!)

My school had the same number of appointments required - I think it's common and I think it's pretty upsetting/bad policy.

As far as your parents please don't feel guilty for burdening them, they are your parents after all. I don't want to say much about it because I don't know your parents but try to rethink this, as they can be a huge asset in this, so just think it over again and decide if it's worth the trouble of hiding it from them or not

take care!

also, about the stuff you took - please consider seeing a doctor if you're worried about it. I know it would be EXTREMELY embarrassing but this is your health we're talking about You could go to general doc or even to your psych.
