Someone fix this Stupid chemical imbalance in my brain

I've been very overwhelmed today, aside with my boiling hot sensitive face that looks like I'm gonna I'm gonna explode that people are concerned about, my mother was upset about me not putting chicken nuggets as dinner, (I didn't put them cuz I hoped she was still gonna cook like she said) but she was busy today. And anyway after that I was having a meltdown while doing the dishes even though I'm being extra dramatic. It wasn't even about the dishes I was just extremely overwhelmed as I said. I hate how I turn small and obvious things into a big deal and it feels like the world is ending. I wish I wasn't afraid enough to be vulnerable to have a hug from someone. I don't want them to regret them doing that to me because I know I will. It also feels extra worse knowing they can feel my every move and heartbeat. It's upsetting because I like hugs I just don't know how to manage them.
