How very frustrating this is and I'm so sorry you are caught in limbo.
No wonder you are discouraged so. Dealing with this pain on a daily basis can wear us down pretty far.....farther than we knew possible at times.
Please take it one day at a time. Days can seem pretty long tho, and sometimes facing yet another day, knowing that there's even another day after that, can almost become the last straw.

It sure does become overwhelming.

I pray that you will catch a break very soon.
