Dear sir , I feel sorry for your current condition. I know how difficult it would be to go through all this. Predominantly you are explaining the mixed symptoms of anxiety and depression ( needs clinical evaluation). Marital disharmony can cause further conflict in this. You need a clinical psychologist does martial therapy and Cognitive therapy.
Please avoid online session and try offline with a expert.
Next Steps
Meet clincial psychologist in your city , who does Cognitive therapy and martial therapy as i do together. Initially you a need a evaluation .
Health Tips
Jacobson muscle relaxation, Cognitive behavior therapy, individual therapy, conflict resolution ( all needs to be confirmed after seeing client )
My wishes for your speedy recovery.
