Mary,
Sounds like you may have injured the frontal lobe of your brain. The frontal lobe controls behavior and holds the filtering mechanism. Also a sign of PCS as I endure this problem as well.
I never used to curse and I was known as patient and calm. Not no more!
I struggled to hold onto a lid of my water bottle yesterday and let out the F bomb hubby just stared in disbelief.
We're all here for you.
Take care,
Kelly
