Am so sorry you're feeling so exhausted and down today, but I know how you feel. I can't drive so have the same problem if I run out of bread or juice or something simple. If nobody can help me I have to walk down to the shops and back with the worry that I might not make it back up the road again.
I've started using a walking stick this week and people look at me as though I'm 100 instead of 30. My boss even had the cheek to ask me what I'd done to my leg today ~mind boggles~ after me telling him just last week what was perhaps wrong with me. And to think that I'm the one that's supposed to have brain fog! He's lucky I didn't use the stick as a weapon!
Check back in here when you get back from the doctors so that we know you're alright! Will be thinking about you!
