Oh, dear.
I could write a long book in response to this. But briefly -- IMHO "God must love you to give you this..." or "God doesn't give you more than you can handle" is a stupid and clueless response theologically and psychologically. I can't believe a therapist said that to you!! UUGGHHH!!
Were you able to find a new therapist?
Only you can decide whether faith -- any faith -- is helpful to you or harmful to you.
Good luck!!
