anxiety

i recently started a new job. i use to only work 4-5 hours a day 4-5 days a week & now i’m supposed to work 8+ 5-6 days a week (which is normal). i’m really overthinking the whole situation. it’s really down to the point where i’m getting sick from my anxiety. if you have any advice or tips pls lmk :(

(i know it’s normal to work that much but i’m just rly not use to it i guess. i have such bad anxiety leaving my home it’s crazy.)
