Telling your friends, that's up to you .. Hopefully they will understand and be supportive.

As for work ? no no no no ... Disclosing to your employer is just never a good idea. Why? Even tho they "cant" fire you over it because of the ADA ( thats a joke getting there help) most people that disclose find themselves a few months down the road fired over some lame reason.

Just my opinion .

I wish you well
