Whats the best way to get rid of my anxiety?

Im 17 years old and i've been suffering from anxiety for 3 years now and I legit dont even know what to do anymore. I've been on paxil, and cyprolex but still no cure. When I do get attacks, I dont only breathe heavily, I also have very bad diarrhea and constant puking. It's gotten so bad this year that im even no going to school and having to be home schooled instead. Please if theres anyone out there who feels the same way or even felt the same way and has cured this gruesome disease please let me know what you did. I really want to get back to my old life and get off these stupid anti-depressants. Nothing seems to work.
