Short Term Memory Loss

I get really frustrated when I have trouble remembering some things. Most of us forget things once in awhile. However, certain things I forget, has to do with CD, or Cognative Dulling, from taking Lithium for Bipolar Disorder. My meds help much more than harm. I missed Home Community tonight and I am so bummed. I only miss it when I am sick and now I keep a mask to wear to attend even if I am sick but it's embarrassing to miss it because I didn't know what day it was literally!
