Hi there
Warm welcome glad you found us...
I've lost more than 5years of my past, its just something I adabted to talking about it is a good thing for me though.
Why not do a collage of pictures of times, places and events...
I think its quite normal it depends on which part of the brain has been effected.
Was your Mum sent to rehab hospital? if not maybe getting Headway involved would be a good idea, speak with you GP
Don't give up though keep pushing.
Take care
