I just walked out of my job. and I'm crying my eyes out now because I could be fired. which I understand but this jobs stress was effecting my health and this one new girl has never respected me and I tried talking to my manager about it and nothing was done. So tonight I wotked with the girl and she got beyond disrespectful many times. to the point I was shaking. I had no choice but to leave. idk what to do. im.so upset and I know I need a job but I was gonna end up getting into trouble if I stayed with that girl. I just wanna disappear

I feel like my hormones are getting worse. maybe turning into depression. I'm so exhausted from havimg a fake smile and being the "Bigger person"
