Sorry to hear about your friends stroke :(
Although I didn't go into a coma, I do know that medicos are generally pretty conservative regarding outcomes. I know of others who were in comas for weeks & know living at home etc.
I hope that things start to get better soon. Please continue to be her best friend, she is going to need you when she wakes up.
Kind regards
Sue
