so i've always struggled with anxiety but, my job in particular has been a huge source of anxiety and stress for me as of late. 

i do therapy with kids, and because of the nature of what i do, i get supervised A LOT by my higher-ups. any and all supervision makes me extremely anxious, because it's more social interaction (god it's SO much harder to socialize with an adult when i'm around kids constantly..) and, feedback is hard for me to hear. i know there's no ill intent behind it, but my insecurities and self doubt get in the way and i assume the worst when they're just trying to help me. 

its gotten worse lately. all i did today was see one of my supervisors' car pull up, and i almost vomited from hyperventilating. granted, this particular supervisor makes me extra anxious because i look up to her and am desperate to impress, but still. that's not something i need right before walking into a session... 

any tips on how to handle anxiety in the workplace?
