I am on an antidepressant for my anxiety and mild OCD. I also take benzos on occasion, but I do not have an addictive personality so I ratio them well. Sometimes I will go an entire year and only take 30 .50 mg pills in total. You have to be careful with those, but they work great for a short-term anxiety fix, but they aren't for a long term solution. I used to get highly anxious and panicky when i would try to eat when i was around your age. there are so many hormonal and emotional changes occuring very rapidly which can cause tremendous anxiety. Are meds an option for you so you can get regulated and try and get your anxiety level down so you can get your appetite up?
