Looking for things to do on my off days

I'm a flight attendant. If you know any flight attendants then you know we have a very flexible schedule. These day's I've enjoyed flying a lot less because of operational melt downs. And plainly I'm just not enjoying it anymore. I'm looking for things to keep me busy on my days off. I signed up to volunteer at the local animal shelter. I sadly don't have my hobbies and maybe that's just because I haven't given anything a try yet. I'm a 24 y/o female. I can't tolerate heat much because of an autoimmune condition. Any other activities I can try so I'm not just home all day bored?
