Feeling very grumpy!

I feel very guilty about my "grumpy" feelings. Being short tempered with family members sometimes. I used to be fairly patient and now when I have flair-ups I am not nice. I have trouble pronouncing Ms and Bs.It causes me pain and when my husband asks me to repeat what I said I feel frustrated.. I find myself distancing myself from conversations..I think this is not a good thing...makes me feel guilty.
