Well the decision has actually been made. What I need to do is tell the other person involved of said decision. I'm still sick and really don't feel up to dealing with the fallout today, but I know the sooner I do it the better for everyone involved. Yes I'm possibly going to be letting some people down, but I do think it's the right thing to do for me at this point.
I believe if you make a commitment you stick to it unless there is no other recourse. So I hope I will be forgiven.
