Hey CB!
Let me answer your question with a question.
When a baby 1st starts to walk is she perfect the 1st time out?
NO of course not.
Repetition is the key to success.
In our situation we are forced to re learn all we once took for granted
as every day minimal tasks.
Well NOT anymore....
Tell you what I did because I went through the EXACT same problems.
What I did was take a medicine bottle ANY medicine bottle and while sitting around watching TV
I would practice and practice opening that blasted thing.
Over and over and OVER again.
After about 6 weeks I was a pro again.
Be patient,
take whatever time you need to learn what you need to learn.
You WILL get better in time.
May not be in YOUR time
but you WILL see improvements more so than if you do nothing and
become toodependant upon others
to do things you CAN learn to do for yourself.
