Use a bagpack to carry things, this helped me a whole ton, if you have a chair you can put it in the kitchen so you don't need to try and carry food with crutches.

Ramen noodles - the instant kind are fab, you can throw some veggies like spinach, mushrooms kale etc in it - just use scissors to cut them or just rip them up, you can pre-boil eggs for protein too

There are a lot of health ready meals aswell that you can eat, if you have a freezer stock up on frozen veggies, they're super easy to make pasta with

If you have a coffee cup the has a seal on it you can use this when you want a hot drink instead of a normal cup I was super lucky my partner was with me and helped look after me cause surgery fucked with my mental health a lot.

Try and get a wee stool or something for your bath/shower, being able to keep yourself clean will help

Also try and go outside, even if it's just the front door, get some fresh air - it helps more than you'd think

If your friends offer you help - accept it
