You told her you wanted to divorce? You went to see a lawyer, or had
divorce papers presented to her? Until they day the legal process is complete (and I don't know where you live, so what the process is there or how long it takes) then you are not divorced, and you can stop that process at any time.
Do you WANT to divorce your wife? Does she want to be divorced from you?
jrobertson is right - the alcohol and meds will affect your judgement.
