Hi a very warm welcome to BTG !
Glad you have found the forum helpful.
In answer to your questions, it really does vary, everyone is different.
I know its very frustrating for you..... I used to get so frustrated I was not the person I used to be. Still do sometimes.
As you say it is very early days for you in your recovery, just take things slowly, rest lots and pace yourself.
There are others on here that have had children post SAH. I am sure they will respond when they can.
Also Teachers that went back too soon. You have been through a huge life changing event, be kind to yourself
Look forward to hearing more from you.
Take care.
