I'm sorry that you having such a tough time right now.
I can really relate to your struggles, I'm a mom to 2 daughters & I've been fighting major depression for too long. I take meds daily, I work with a T, but I still have a tough time with life.
Maybe you should call or em-mail your T, to see if you can get some of your latest worries of your mind? Or write about them in a journal, and be better able to let go of these dark thoughts. Gentle hugs to you...
