Offering Help and Coping Skills for Depression and PTSD

I am starting EMDR on Sept 1st to treat my PTSD, anxiety and panic disorder, and depression.

I need someone to talk to about the way I have been feeling lately. I can't get these negative thoughts out of my mind. I am feeling like a worthless piece of shit and also feeling as if I were to just end it all no one would care.

What kind of coping skills would you recommend for those of us with all the above mentioned, but also doesn't have a creative bone in their body & are physically deconditioned & cant move great or walk well & not supposed to leave the house & limit visitors for medical reasons?? I'm getting kinda fat. Found myself eating more as a coping mechanism. So, I've been watching what I eat now & I'm starting to walk super slowly with supervision on my Moms treadmill. Itll be a year at least the doctors originally said, until I would be allowed outside more often & could do physical therapy & all, but everything is moving stupid slow. I am 8 months sober & at home with my Mom & my depression & PTSD has been coming out in my dreams more often now. & I just feel so totally helpless. I need help doing ANYTHING. So, yeah...whatcha think? I cant free hand write or color. My hands shake too badly. I can type alittle but I rely on talk to text a lot. Thanks! 💕🤗
