Offered electro-convulsive therapy assessment

After going to the emergency room in a state I asked for ECT and I will be assessed for it soon. After thirty two years of depression pills and therapy I guess it’s the last throw of the dice. I fundamentally don’t want to live and certainly don’t have anything to live for so I doubt It will work. Of course when it fails I’ll have no option but death. I’ve had enough depression and fear for a lifetime, thanks.
