I am so sorry you are struggling so much with anxiety and depression. Sometimes it is so hard to distinguish between which one is bringing on the other. They seem to work together all the time. I don't really really know your situation fully so I can't tell you which is which for you, but for me it seems that my anxiety makes my depression much stronger. If I seem to get my anxiety under control then my depression seems to follow. I really think this is something you will have to realize and work through and maybe with the help of therapy figure it out. I wish you all the luck in the world because I know how hard it is dealing with both anxiety and depression.
