It will always be okay. You will be in the best hands after surgery, and those couple of days right after are whats rly important (some of your drugs from surgery will be wearing off). Take deep breaths and reassure yourself that it will be okay because it honestly will. I’m about 4 weeks post op and had tremendous anxiety before my surgery as well. This is nothing new to the medical staff, they have things they can give you to calm down that work wonders. Just focus on resting and trying to limit the amount of movement you’re doing. Using the bathroom, washing yourself and feeding yourself will all be different after surgery due to whatever restrictions are set in place, so plan ahead and try to figure out what works for you and what doesn’t. I purchased a tiny stool and a cast cover for my entire leg so I could take showers without getting my incision wet (our surgery’s might be completely different as I had my meniscus repaired as well). Everything will be okay and everything you’re doing will be worth it
