I start work tomorrow at a big box retail store, it's just a 3hr orientation with 4 other new people but I'm still so nervous. It's about 30 mins from my house/safe zone and I'm low-key flipping out just dreading it. My head's like "what if ______ happens", "what if I ________", etc. I've quit on the first day of work before because I was so overwhelmed and I dissociate really bad and get physically ill. Please help.
