My therapist is having me seperate myself from the negative impulse thoughts like "i am a horrible person " etc. So that i can look at those thoughts and be like; that is not me that is my depression, so don't let the negativity affect my actions. This has helped me and it has also helped to put all the self-deprecating thoughts under the depression umbrella and to try not to beat myself up for the things under that umbrella.

I hope that helped, and thanks for letting offer an opinion nonetheless.
I wish you luck and good things
