Your troubles are not of your own making. Nor will they be solved entirely through your individual effort. A single house's fire threatens an entire city.
It is natural to turn inward, and forget the world, to fall asleep, and become alone with our thoughts in the quiet. There is an importance of talking with neighbors, to express that friendship we feel, to remind them of our own presence: they would regret forgetting you, or not being aware of your need. And it is important, too, to remind ourselves that our friends are there, that we are not alone - as we might regret forgetting they could help. If we permitted ourselves only to be aware of those who were hurting us, we would think the world a dreadful place. But it is much bigger than that. You are surrounded by friends. And restoring friendship with those who have hurt us is also not beyond reasonable expectation. Any more than it is not unreasonable to expect, upon reaching out, to find yourself surrounded by those friends who were always there.
We share one world, and one community - you are an important part of it. It is natural that everyone would care for your well being, as much as their own. For your interests are the same.
