Ever since I started to truly enjoy my job, any amount of criticism literally makes me feel like I’m gonna throw up. I go from upset(verge of tears), pissed off &amp; eventually just try to let it go. My manager just told me to ‘be careful’ doing something (I thought I was helping a customer) and now I feel like “well I’m never going out of my way to do something nice for another customer again” 🙄
