Hi knitkitt,
When you were shopping in Wally world, did you use one of their scooters? I remember at first it made me feel sicker than I was, but they do give us more independence! When you aren't so worn out, you can shop longer!!!!
Please try getting out as much as you can now.....there may come a day when it's just about impossible. Last trip to "Wally" or anywhere other than a doctor was over a year ago. It's too exhausting getting ready, having someone force my legs into their car a couple times, etc. Being alone adds to the problem, even so-called good friends don't want to bother.
So start using those wheels -- that's what they're there for!!!
Hugs........
