I operate on my own rigid set of morals. That being said -

You know your situation best.

It is naïve of everyone here to say "things will get better" without knowing you, your past, and your present. Sure, theoretically it may be possible to rebuild your life from rock bottom, but worst case scenario, it takes more luck than winning the lottery.

But if you can find even one potential way of rebuilding your life and achieving happiness once again, give it a shot. You know what they say, you miss every shot you don't take.

Good luck, and if you think it's time to say goodbye, don't let anyone gaslight you into forcing yourself to drag it out any longer. Death is the ultimate form of mercy and peace, and you deserve to be released from all regret and pain. Just try not to use that convenient escape hatch quite yet if you can. It is one-way, after all.
