I know too well how you are feeling. Something that is helping me now that I will not see a therapist until the summer is a book called, the art of emotional healing by lucia capacchione. I had started to use it with my therapist, but I ran out of $ to continue therapy. But I continue to work with the book. I am far from an artist and it took me a few exercices to accept whatever I draw, sculpt, paint, write or even dance.
I found this to be different than the CBT I had done in the past. I don't need to change my thoughts to do this, I just need to go with the feeling.
It helped, but I am certainly not out of the hole yet, just climbing slowly.
Take care
Carla
