i start school (first day orientation) 10 days after my surgery and i’m really nervous

i dont know what to do, my doctor told me the school thing is fine as long as im not sitting down for a long period of time each day but i’m really worried that 10 days is a lil early and i might not heal properly bc of it. school is extremely important to me! i’m thinking that i may have to take online classes but i’ll still need to get up and go to my clinicals obviously. how was day 10 for you guys, i know every body os different but i am curios? am i making a big deal out of nothing or is that a lil too early to be moving around. i physically start 3 days after.
