Pam -
my best advice is to return part-time for a week or two if you can. Then if that goes well, return full-time. That's what I did and I found it helped tremendously.
As for your staff, you don't really have to prove anything to them, but it wouldn't hurt to explain some of the "new" things about yourself if you feel comfortable with that.
I remember telling my staff that I was SSD so if I didn't respond to a question, or gave them an answer that just didn't make sense, it pretty much meant that I didn't really hear what they had asked me

I also mentioned that my balance was still adjusting, so that while I was a little "wobbly" it wasn't a major concern nor was it cause for alarm.
I think that I - and all of my staff - felt more comfortable with me addressing the issues rather than just ignoring them. But what you choose to do might depend on the type of relationships you have with your staff members. Just go with your gut.
Good luck,
Jan
