Can you relate?

I’m 21 and I don’t know what’s wrong with me. I feel like I’m 80yrs old. I can’t for the life of me remember things like the plans I make with friends or the day of the week or even what shift I work tomorrow. I can barely control my bladder and today at work I peed myself all because I wasn’t u doing my pants fast enough. This is more than embarrassing for me. I think I have a yeast infection and I’m just uncomfortable in my own body. Please, any advice is more than appreciated
