I had a brain tumor removed in 07 but in January of this year I had the first of two seizures in almost 4 years. Now when I get stressed I become unable to speak or slur my words. It's like I know the idea I want to get across but can't think of the words to articulate it. I practice breathing exercises and sometimes take valerian root to calm my anxiety. There's no shame in explaining that you need a minute to collect yourself. I find out Tuesday if I have cancer again.
You hang in there too dude! I'm wishing you tons and tons of good luck and good vibes, I hope you get good news on Tuesday.
