To birdie 94 you sound as much aspergers as she is .Which could be fine if you understand it.
I am pleased that you and Ash are good friends, and like each other. It is good thing for friends to understand their friends sometimes like to have times to themselves to be alone with their own thoughts if they want to.
I think you have spent a lot of time putting your own thoughts in writing your email,with your your special thoughts.
From your email, you appear to be a very special person like Ash, who needs help some times, If you have any problems I suggest that you see your own doctor who knows you personally and who may point you in a direction to help you.
If you wanted to, you could always show your doctor a copy of your email letter and replies, as it will save you trying to express any problems to them having done it once before in your email.
Good luck with your freindships. Stay Happy.
