Cleaning yourself with a broken ankle?

On Wednesday evening when I got home from work I was getting out of my truck and I slipped on some ice and broke my ankle 😢 Thank God my boyfriend was gone so he could help me up and take me to the hospital right away. I need to have a cast on it for minimum 6 weeks, does anyone have any tips for how I can wash my hair and suck alone? My boyfriend works 15 hour days so I hate asking him to have to help me with that, and advice would be greatly appreciated!!
