Oh boy, another lost, toxic dude looking for advice because he can't afford counselling but for what it's worth thank you for reading!

Okay, where to start. I suppose the crux of my issue is that I keep finding myself getting caught up in my own bs feelings and "riding that wave" for lack of a better term. In those moments of hurt, even ones quite trivial I find my brain really putting time into fixating on it and boy gee do I feel genuine hurt. I find myself getting so stressed and worked up to the point of loss of appetite. Obviously I can look back objectively and see exactly what I'm doing wrong but I just can't seem to catch myself before I allow them to get blow out of proportion in my own head. And boom, I'm being a butthead to the LOML. 

My partner and pals think I've recently developed anxiety over my previous (really not good) relationship and a SA that both took place within the last 2 years which is pretty spicy and something I need to put the research into but it's quite overwhelming to hear in your mid 20's ya know. 

Okay I may have down played the loss of appetite thing, I think I eat a tiny meal a day and started stress vomiting. Why is my noggin hurting my stomach so much :( 

TLDR: I'm fixating on issues and can't seem to find up with a method to catch myself before I fall too deep into the hurt. Does anyone know good methods that might help me get this under control?

Excuse me if anything is unclear, I'm certainly no wordsmith or eloquent enough to do better right now but I'm happy to elaborate further if anyone wants to know more! 

Thank you!
