I am sending my love and well wishes <3 you don't sound stupid at all, and I think it's courageous to want to take the step forward to reach out. That's never an easy thing to do.
The world is in a weird space right now, to put it lightly, and I can definitely empathize with feeling depression and urges to relapse resurfacing (with cutting and w suicide.)
I have a few things, as far as advice goes that have helped me out!!
As far as relapsing goes, the way my therapist has me view recovery, is that it's more like a scribble than a circle.
The path on recovery constantly changes and warps, sometimes it repeats, but it changes as we do. Cutting again is never an easy scenario to deal with mentally, but, it doesn't mean you've stopped recovering or getting better. Sometimes we crave what we found comfort in, even if it hurts us significantly. I relapsed recently, too, and it doesn't mean you're on the wrong path <3
Whenever I get strong urges to cut, I try to go to anything that's very cold to distract my nerves. I.e holding a cold pack to where you want to cut for prolonged periods, holding ice cubes, splashing your face or arms with very cold water, etc.
Rubber bands on the wrist have helped out a bit before to curb the immediate pain response for a bit, but, be careful w those! They can bruise sometimes, so I try to use them lightly.
I know everyone and their dog has been talking about establishing a routine in quarentine, but it's definitely harder if you have depression, or if you're neuro divergent.
What has helped me out, is to just find one comforting thing a day to keep me company. Be it making tea, gaming, drawing, etc, whatever will keep you occupied.
It's okay to have bad days right now, too. You're okay to feel stress and fear, and it's okay to take time away from the news or from people to just focus on you. That's not a selfish thing, if you want to work on your state of wellbeing.
I've been on the path of recovery for a few years now, but actively since early 2019.
It takes a lot of patience sometimes, but, I can tell just by reading your post that you've got an amazing heart, and determination to match, even with all of the pain you're experiencing.
I still relapse, I still lean into wanting to ctb, but, I am still getting better day by day.
I'm hoping that things can go up for you, my friend <3
