Talk to your mother: Try to persuade your mother that you need professional help. It is dangerous to try to treat yourself.

Call 911: If you think you are in danger of harming yourself now. Otherwise, call a suicide hotline or at least speak with the people at your school. You list "hopelessness" and use the term "desperate". There are people who can help you either get out of your present situation or manage the attitudes of those around you and guide your own thinking / need for meds.
