Vent! Feel like I’m going crazy!

I legitimately feel like I’m about to lose it, just flip out go crazy and literally cry for days. I’m not myself anymore and it’s the scariest thing I’m going through. Sometimes it’s such hard work to smile or even pretend that I’m ok. I’m just so exhausted, I’m tired, I’m sad, angry, and so vulnerable. I get so bothered by simple comments, I get bothered by disobedient children of my own, I literally feel like just running away - not from my family but of myself. My thoughts race, and I get so overwhelmed to the point where I have to just walk away and remember to breathe. I need a vacation from myself.
