Struggling with the decision to use a mobility aid

I’m struggling with giving in and getting a mobility aid. I had a walker at my worst, but fortunately when back at work I was in a wheely chair to get around, or have the ability to stand or sit as needed. When out, I generally am at a store I can use a walking grocery cart. I can’t stand for too long without assistance or I get extremely weak and fatigued and struggle. I think a cane will be a good option, but I’m fighting my pride which sounds dumb. But I keep feeling that other people have it worse and I should suck it up. Same for using my parking pass. Anyone else in the same situation?
