Hi Embrey and welcome. I am sorry to hear about
your severe anxiety/panic issues. It is very difficult to navigate life while dealing with such things! I am glad that you have found us, and encourage you to post anytime you have quesions, or just need to share and get some support from people to understand:)
To answer your questions...
Yes, you should gather your personal medical records and get them in order. Make the calls as soon as possible, as this may take awhile.
I don't think that you need a lawyer at this point. There is the Mental Health Disability Act that should ensure that you get the coverage you need.
Here are a couple of sites that you will want to check out, as well as your state's individual laws.

I hope that you get the help that you need soon. Trying to get through the red tape of this kind of thing can be tough. If you can get the assistance of a friend or family member, that would be great. Again welcome and post anytime.
Good luck,
Scaredy Cat
