Hey Crystal,
I'm sure a lot of us have experienced the "I'm crazy" thoughts at one point or another in our recovery process. I know I have and I think a big part of it is my lack of "filter" since the injury.
Prior to the injury, I was patient, level headed and always concerend about others feelings. I still am to a degree, but it is now much harder for me to control what i say... either due to pain or medication or just TBI....but it makes me feel as if I've "lost it".
Hope you find the right med combo that works for you....I have been doing the same to headache meds.
