As-salamu alaykum, brothers and sisters. Does hurting yourself ruin your fast?

Assalamu alaykum. I've been struggling with depression for a while now. Most days, I'm okay, but sometimes my mind just gets overwhelmed and I end up feeling really down and even having thoughts about hurting myself. It's like I'm not in full control when those moments hit, and I act without thinking. Ramadan is always tough for me-it feels so lonely, and honestly, it makes my depression worse. I used to get so excited for this blessed month, but now it just brings me sadness and fear that I might do something harmful. Even with all this, I really want to keep fasting. If I do end up hurting myself, does that mean my fast is broken?
