I have no memory issues, no cognitive issues etc... All my symptoms headache noise sensitivity start once I start getting overloaded. A half hour conversation w someone can do it..reading too much. 10 mins on computer or tv

So how do I get thru the day? I'm sick of isolating myself. I'm sick of crying.
I have 3 kids and I need to function more w out getting stabbing headaches from overload

I need a plan. Any suggestions out there?
