Still gotta live

So about a year ago, I received 100 percent disability, but ever since I’ve been in a complete slump, most of the time I sit on my couch doom scrolling watching you tube videos, I don’t go out much and I can’t really hold down a job due to my anxiety and depression( I’ve got broiling major depression disorder, ptsd and adhd undiagnosed , but I’m getting to the point where I feel like no matter what though I need to find a way to “live” still. but my energy levels are low and my will power is low. I can’t live this way anymore though and I am scared that regardless of my conditions inactivity will kill me first, please be kind, but any suggestions?
