Hey Pitbull,
Anxiety and Panic stem from and are related to depression. When it gets serious enough, the symptoms manifest in your body as physical pain. That is chronic if you've been suffering for a period of time. My anxiety came out as neck pain, stomach pain and general ache in my whole body. Point is go for chronic pain because they don't have an anxiety box listed and you will probably get turned down if you check the "other" box.
