feel like an embarrassment

i wish i was able to sleep but every night, i can’t stop thinking about the past day. i feel like i’m an incredibly awkward person and struggle handling myself socially. every day at work i feel like i make a handful of fuckups and they just sits with me. the ones that hurt the most are some interactions i try having with coworkers and i feel like i just end up embarrassing myself. at the end of the day i just want to explode thinking about it all and would rather have people forget i existed. i just feel like i’m too awkward for my own good sometimes and i can’t help it. how do i cope with this
