Then stay consistent.

Did your counselor give you any suggestions or exercises to help you stay healthy?

IMO means "in my opinion".

I would say that you should continue to work on your job prospects and maybe if you have the time, you could volunteer somewhere and help others less fortunate. As bad as your sitch seems there are ALWAYS someone who are worse off than you. Helping them might help you to appreciate the gifts you have right now and start to rebuild your self-esteem.

Stop thinking about your H and the OW for awhile.
