I hope you're feeling ok after your fall - I fainted and had a concussion earlier this year. I was very spacey for a couple of months so I know where you are coming from.

I wouldn't worry anymore about forgetting her birthday. Maybe you all can meet up for a drink or lunch and you pick up the tab, if you want? I don't even think that's necessary but just an idea.

My best friend, she and I met several years ago. We forget each other's birthdays all the time. It's no big deal. We made it a point to not stress over it when one of us forgets lol
