I’m always anxious and cant stop hurting myself

Ok so quick CWs for talk of suicidal ideation and self harm.

Seeing as I’m (23NB) level 1 autistic, I get overstimulated a lot. I’m also not living in the safest environment for me emotionally and mentally but I can’t move out either.

The thing is, is that this constant overstimulation and negative environment has led me to try to self-soothe through biting. I’ve bitten bits of my tongue off, bitten wounds into my chest all the way down my legs, I’ve even bitten my feet. I’ve tried not to obviously but not biting almost makes the pain worse??? And not biting just makes me anxious more. It also leads me to resorting to sharp objects or things like clippers to get the same effect.

I’ve literally traumatized the nail bed on my left big toe so bad that it will never grow back right. All because I just went at it with the nail clipper. I’ve been trying to stop myself because I know it’s bad.

My mom says I look like a crackhead or a junkie because of my facial marks now. But not biting or picking at my own body feels like torture from all these tense feelings in my body.

I’m scared I’ll get to a point where I can never recover. My tongue is getting open wounds and swollen spots it’s so bad but I just can’t stop.

This is mostly a vent but any advice is welcome too. I do have a therapist, I take anxiety depression and mood stabilizer meds and I’m getting a psychiatrist soon but that’s mostly for dosage refinement.

Please help or just let me know I’m not alone…
