To anyone reading this: don't lose hope.

In a situation like the one you describe, I received help from a complete stranger I met on FB. I don't know if this is a basic rule of life for all people, that in difficult times, people close to you, and those you could otherwise or thought you could, logically, rely on, pull away, as if misfortune were some contagious evil that could be transferred to them if they interact with someone who has had something like this happen to them.
This affected me in a very special way. And I no longer consider myself to be the good person, always ready to help, that I used to think I was. But there is always hope. Help comes most unexpectedly, along unknown paths, through unknown people, always incognito, always quietly, always from people who don't want anything in return.
And I'm not the person anymore who could give advice or encourage anyone after all this, but I can tell you one thing: Hang in there girl, because we have no other choice! And know that you will always receive support, you already know it yourself!
