I totally get this ... through this situation with my leg, I've wished I had a partner, too, especially for the first several months when I needed a walker.
But here's the thing ...even if you have a partner or roomate, things can happen when they're not around. It's like people saying they want to be married so they have someone to take care of them in old age. There's no guarantee the other person won't die first. Or be the one who needs caring. Or what if it's both of you??!
Best thing we can do is learn to get through each moment as safely as we can, and let the future moments unfold one at a time as they will do, with or without our fear. 💜
