I feel like it's never gonna stop.

Long story short, i've cut someone off a long time ago. The relationship was a catastrophe. It was like 80% negative and 10% positive moments with that person. My very very VERY last straw was when my assaults got denied by that person to prove a point, and that happened after weeks of gaslighting, neglect and taunting . I had a serious mental breakdown and shouted as hard as it came, then cut off that person after hours of spiralling.
Now i found out that this person made posts on me and other people that went against their bs. I also found out they made a whole account to shit on my people.

I am so done.
It's been a week since i've been out of these suicidal thoughts situations. I was so happy to see that i was improving, and being a decent human being for my loved ones.
Now i'm back to spiraling and just ending everything for good. I don't know what to do.
