I was a sick child, and to be honest, I loved it - it was easier learning everything by myself, I watched cartoons, read books etc. I always found something to do.
Now, do you have a list of things you wanted to do at home but never could because you didn't have time to do it? Like a list of novels, exercises, things to arrange, etc.? I've started to write words and letters with my left hand when I was sick for a long period. I didn't stop, and that's how I became abidextrous.
Get better btw!
