Fat Tuesday or Therapy Tuesday?

I haven't been to grief counseling or to the therapist in about two weeks.  My next meeting with the counselor is tomorrow night and my next therapy session isn't until the 29th.  Tomorrow night is also Fat Tuesday, a holiday that my friends and I are pretty big on.  But this year, I have to be up for work by probably about 4 am the next morning.  I'm torn between skipping out this year or just saying, fuck it, and calling up Rosie to tell her I can't make it this week.  But would that be smart of me considering the fact that I've been drunk for about 6 days straight at this point?
