Get a check-up, take your meds, and read this
book. (Dumb title, great book.) The premise is that the dialog running in your brain drives how you feel. I still feel anxious at times, but now know that evil little voices in my mind are causing my reactions. The anxious feelings decrease as soon as I realize what's causing them. That inner dialog can be nasty! It's depression when those voices are tormenting me about the past, and anxiety when they torment me about the future.
Hope you are feeling better soon. Funny thing I read about depression: "Depression is anger without enthusiasm."
