Dropping out

I’ve been given temporary leave from college as I can’t make it in due to my mental health but this week I have to make the decision on dropping out this year. My options are doing a levels online, do the restart program next year at my college or start working but at the moment i can’t do that. I think I might take a year out but I’m not sure what to do for a year while I’m off college? Any ideas?

Also I’ve dropped an a level next year I hope to do 3 at college but if I choose to stay with 2 how much does that restrict me with uni choices?
