I think that exploring someone’s suffering through the roots of their childhood might be helpful at some point but not at the brink of despair. I have been going through the same issue, feeling lost and in despair after my break up, and there’s not much we can do about it. You got to feel what you got to feel. Let all emotions come to surface and one day, at some point, you will feel that enough is enough, at least for that time. Talking to people is also very helpful, don’t hold your emotions or feelings, and most of all, when you feel like you’ve had enough, surround yourself with good things, such as books, series, going out with friends, whatever nourishes you. Accept what life brings you, what happens to you. Don’t question it, live it.
