Well, THAT sucks!
Do you have an old pillow you can beat up and scream into in the meantime? OR, you can sign up for kickboxing lessons. Watch some really funny movies or do something that includes some deep belly laughs. If you're into nature, maybe you can schedule some quiet time out in the woods to just "be" for a little while.
Sometimes little things come along to remind you that life is worth living. Sometimes things happen that make you grateful you didn't carry through with suicidal intentions.
I hope you can find some balance while you're waiting for treatment.
