You are acting out your own demise, like it is some carefully scripted movie. See your previous post - every sentence you start is about someone else and how they didn't come through for you.
You have to start acting out your own positive future - it won't feel right at all - it will all feel fake, because it actually will be.
Ditch your old world and way of thinking and acting out, and simply go and DO whatever that it is you want to become. It's like giving up smoking - it hurts and it feels wrong, but you just keep doing it and it works out.
Just start with small things and small successes. If something doesn't work out, do not be tempted to use it as proof that it will never work out - this is the same trap that you are trying to get OUT of. You are in control, not them.
Do not be tempted to hold others accountable for your lack of success. It's just too easy to complain that it's their fault, but it's not - it's yours.
So start today.
