Please help with consumed thoughts 😞

I’m desperately seeking help with my consumed thoughts that are taking over my life right now.
A brief background:
I recently returned to work after a traumatic incident following severe bullying and discrimination. When I returned I was shocked that many colleagues/friends were hostile to me, as they stayed working with my bullies (there was no discipline in the end). While I did have some support, I’ve found it difficult when I’m face to face with these others that have chosen to be hateful without even reaching out to me. It’s a complicated case.
Well last week I was in the office of a former friend I guess and I was caught off guard with the conversation. I’m not great on the spot as I usually need to digest what’s being said before I can respond properly. Long story short I didn’t say what I should’ve said to defend myself properly. This person represents a big group that has treated me unwell for a long time.
Here’s where I need help. I know it’s one thing to just say forget about the event, but I can’t. I have been so consumed with these invisible conversations. I should’ve had nonstop for the last week. I can’t eat. I can’t sleep. I’ve been pulling my hair out. I do get consumed with thoughts, but for some reason, I can’t seem to break out of this. I feel like I missed the biggest opportunity ever to make somebody understand something so big even though I know it doesn’t matter.
I’m so close to even texting this person to seek out another conversation even though I know it’s a bad idea.
Someone please help me heal. My brain is eating itself up.
Does anyone have tips to break this obsessive cycle?

Hey hey @asro 🩵
I don't really have any tips but I just wanted to say that it's clear how much distress this was/is causing you and I hope you're feeling better by now.
I find the Exploration Garden Group Room here is helpful for processing situations similar to this, if you wanna try that. You're always welcome to join us there. 💙

Meditation is difficult at the beginning but very beneficial . When you start and the thought flood in just think “I am grateful for this moment just as it is” and try to resume. Keep doing this. It works if you work it. Even if for only a couple of minutes
