The thing about psych meds in general is that they're not one size fits all, unfortunately. I've been on three antipsychotics at different times because they can also be used in bipolar patients, and they definitely all can come with their risks and benefits. Don't get discouraged if you do have to raise the dose or change to a new medication entirely, because you'll find the med combination that works the best for you!

You definitely don't have to tell the teacher who isn't understanding of mental health, but it was great that you did tell the other teacher that you self harmed, even if you didn't tell her why yet.
