Welcome back, Alena-

Sorry you're on the limbo track----have your docs tested for lupus? My sister has lupus and has many of your symptoms---including very sore joints, as she also has osteoarthritis. The damned autoimmune diseases seem to run in families. Any of your relatives have autoimmune diseases?

Rheumatologists here usually treat lupus. How about there?

Take care, and keep your spirits up. Demand antidepressants if you need them! I certainly was depressed going through my 2 year diagnosis procedure!
