Deb, Hope springs eternal. I am hoping your sister will get over herself and I am hoping that you will hang tough with that same hope in mind.
Many drug companies have 800 numbers and real people to talk to...could you swallow your pride and call them...explain your present circumstances and see if they will help with the prozac. I hear you when you say that you don't want to ask/take help but you are worth it...your children want their mother alive....so do we.
