anxiety is a horrible thing to have to deal with and it sounds like it really has its grip on you exacerbating your depression. I have an anxiety meter I use that I dial down my anxiety with when it gets to high. basically you imagine a meter in you head. a dial from 1-10 that you rate your anxiety on 10 being the worse. there is a red zone from 8-10. you use your breathing to reduce your anxiety to get the meter out of the red zone to a more manageable level. I actually turn the dial down manually to get it out of the red zone and it helps. so when my anxiety is all jacked up, I just tell myself to dial down and it helps. it helps if you practice it in a meditative way a bunch of times first. good luck.
