I'm sorry to hear about your son.
You do have a difficult situation, and I have been in those myself.
If you are a bipolar, were you on any medicine when this began?
Are you on any medicine now?
As a bipolar myself, I am on lithium for the mania and Mirtazapine anti-depressant for the depression.
It helps me get through some difficult times.
I've had to change jobs, also, to get into some lower stress situations.
Are you seeing a doctor for the bipolar?
How about for the Crohns disease?
Have you seen this website's Crohns disease forum?
Are you in physical pain from the Crohns?
