I'm sorry Prop.
It happens.
Don't worry about career and reputation, focus all of your energies on remaining sober. It's never going to work out if you continue to drink. Get the bipolar in order. See your doctor.
You are fortunate
to have parents who can house you, some people don't.
All you've got to do is to not pick up. All else will fall into place.
I hope you've stopped.
