how long until you could be alone for a while?

im having meta (vaginectomy, scrotoplasty, no UL) at the end of july and im worried about whether my partner is going to be able to get time off of work to help me. (we work in the same place btw)

they only work weekends and i'll still be in the hospital for the first weekend post-op, so i'll have a week with them home, but they don't have enough vacation time to cover even one shift (10 hours) and while we're Allowed to take unpaid leave, it really seems like they don't want us to and will only approve it if theres no other option. we also have caregiver leave but i don't think they'll be able to use it since it specifies that its for caring for an immediate family member or spouse and we arent married.

we know basically nobody in the area we live in and everyone else in my support system is a) over an hour drive away, and b) generally pretty busy. so its unlikely we'll be able to have someone else stay with me while they're working.

i know it depends on a lot of different things so i cant be totally sure, but is it Likely that i would be fine on my own for 10 hours at a time, 2 days in a row, ~1 week post-op?
