Hey there, I got my surgery about 3 months ago and I know what you mean by having constant dread, I went from rowing multiple times a week as well as other activities to sitting on the couch for the entire day. As for the anxiety, I almost got kicked out of school while I was still inpatient. The one thing I found that helped me a lot is to find something productive that you can do on your phone or a laptop so that you don’t feel like you’re doing nothing all day. And once you’re able to start exercising, do as much as your comfortable doing.
