I’m worried about my mom. Will she be okay?

My mom has always had a lot of medical issues. She has arthritis, pulmonary issues, lupus, etc. She had breast cancer when I was younger, but is fine now. Recently, she has been put on oxygen at night, and her white blood cell count is low, so her medication was changed around a bit. I’m sure she’ll be fine, but I’m starting to get worried. She’s 60 years old, and I just always worry about her since she was in the hospital when I was younger. I’m sure she’ll be fine, I guess I just needed to vent.
