Well that person is very confusing, to say the least! This sounds like you did absolutely nothing wrong, and I do not understand the other person's accusations.
I can understand wishing to be in a coma. Although I realize it is an unhealthy thought, I have sometimes thought that comas were the only true rest I have ever had.
I hope you get a break soon. You need it, and I concur with newtus that you deserve it.
