Leah,
It is very difficult for someone who has not walked in our shoes to fully understand what being a stroke survivor entails. We have good and bad days just like everyone else; however, with us our deficits can and do have a greater impact on us.
I am 3 years post; I still have times when I need to retreat to the quiet confines of my room until I am more relaxed and able to deal with everyday life - things that before the stroke I accepted as the ways things were. Stress is believed to be a cause of stroke and none of us want to have reocurrences. Take the time for yourself, be gentle with yourself. We are our own worse critics.
You're a survivor and you're not alone.
