I have a few suggestions. If you haven't already done so, talk to close friends or family you trust. Sometimes when it's really rough, it's hard to advocate for yourself. Talk to your designated school counselor or guide for which classes you take. Explain what's going on. S/he may be able to speak on your behalf to your teachers, or help set the stage for you to if that's not possible. As far as your medication goes, when you have bad reactions as strong as you have had to your anti-anxiety medication, talk to your doctor immediately. Follow her/his instructions carefully regarding discontinuation. Ideally, you'll be prescribed a new, effective and not-at-all-horrible medication in its place. I know it's hard. Keep in mind that you can and will feel better. I wish you all the best.
