OP you lost the equivalent of 2 new corvettes?
And you think gambling is killing you?
Look on the bright side...

This person smokes pounds of crack, has probably had her children torn away from her, might live in a box some nights, and sucks people off for a living.
She's probably happier than you.
I either choose to pick life or pick the slow death of a casino. I have gone to GA and counseling for over 2 years and gambled the entire time.
OP, if I were you, yes, I'd probably go to the doctors and tell my problem had more to do with suicidal ideation, rather than gambling.
Casinos are everywhere, and people gamble. Fact of life.
Are you on any medications?
I tell myself everyday that life like this isn't worth living.
I don't know you, but you sound like a suicide case waiting to happen.
Life is actually very very good, even when crack cocaine dominates peoples lives, they persevere. I think you are depressed and after years of gambling, the heavy losses are hitting a mature person harder...
So... yeah... learn to live with less, or stop thinking rock bottom is not worth living...
Wish I had something different for you... but that's all...
