Recovering Japanese ability
Thank you for the advice!!!!!
I had the opposite experience.
I was learning English then had a long break for some years, and back again.
My English got quite rusty over the years of not caring, but just like Steve said, all the knowledge is in a storage somewhere in your brain. That is for sure.
All you have to do is to take it again like before and you'll see the light.
Just keep at it for a while and you will right back to where you were. It is all still in your brain waiting to be reactivated.
