Content warning mentions of anxiety, chest pain, confusion, death, lupus etc

Hi everyone, I'm Kaitlyn 22 F, and mom to a toddler. I'm typing this after my shower and I'm in bed in my pajamas but I'm so anxious. I can't stop thinking and overthinking. This morning I got a chai drink with a shot of espresso at my local coffee shop and then I took 20 mg Adderall as well this morning and holy shirt balls the ride I've been on today has been the absolute worst I thought I was genuinely gonna die this morning. I had to work at 10 and I was able to get to pull myself out of the bathroom at 10:07. I was doing my makeup before work and it started with the shakiness and the jitters, then the dry mouth, then nausea, then chest pain/pressure in my chest, severe confusion.. lol I was steaming milk at work and starting pouring the milk all over the table :( I was so embarrassed I just had to go to the bathroom and sh!t my brains out for the 5th time that morning. I was able to make it through my shift but I'm still feeling this way even after so long. I just got back from trick or treat with my toddler.. I can't make the what ifs go away. "What if this isn't because the caffeine and Adderall"? (Which I know it's highly likely that it IS) "What if there's something wrong with me because my period is late"? "What if my autoimmune panel comes back and I do have lupus"? "Am I gonna just die tonight because of how bad I feel"? I'm tired and in pain and I'm mentally exhausted:(
