Assume that you only have the resources and money that you’ve acquired up to this point in your life, and you still have to pay rent, bills etc. You are basically physically capable of everyday activities but extreme feats (eg running marathons, climbing everest) are not realistic.
If your family would be upset to lose you, I imagine they love you and they would be upset no matter the way it happens. You might be trapped now, but life is long and full of opportunities. Luck is when preparation meets opportunity. Seek help, go to therapy, work on yourself and grab life by the balls. This humble stranger on the internet believes in you.
