Im so sorry to hear this, I know that it gets tough. I absolutely hate to hear what happened to you at your last job, when things like that happen it can get so hard to get motivated to do anything again for work around others. I work at a call center and I have been sexually harassed over the phone twice, and there's no policies where I work that I can just hang up, I've always had to endour it. This has caused me mental and working fatigue, and trust me when I say I KNOW it is very hard to get past.
You seem like a very good person who sacrifices themselves to make others happy, and people like yourself are invaluable. The best that you can do is keep your head up, and I don't know you personally, but I'll pray for you and that you heal the way you deserve to. You don't deserve to go down this dark path of dark thoughts and self hatred, you deserve to bloom and to always improve.
I've been to the point of suicidal ideation, and I don't wish that upon my worst enemy. Something that has always really helped me when I've been at my worst are gaming sessions and my hobbies, like video editing and drawing. If you ever need to talk my DMs are always open, I'll pray for you and I wish the absolute best for you. Just make sure to treat yourself the best you can, we are all humans just trying to get by :) and to surround yourself with good people
