This is a very sad story you're telling yourself about your future. It makes sense because you feel sad now; you feel terribly sad because you've undergone a horrible loss and rejection, something no child should have to suffer from their parents. I'm so sorry you're going through this, and so sorry that you don't have friends and loved ones around you at this difficult time.

I can't imagine how much this hurts.

However, please give your transition a shot. Six months into a second puberty is not very long. I saw your progress pics and you're going to be very pretty, but it takes more than a year to get there. Stick it out. And please seek help for what is a very understandable depression compounded by grief. Listen to music you love. Eat spicy food and chocolate. Look at art. Let your friends have the pleasure of loving and supporting you. Remind yourself of the benefits of being alive in the world.

The sad future you're imagining will almost certainly not come to pass - the real world is much stranger and more complex. Grieve what you've lost, because it's a terrible, terrible loss. But don't despair of your future.
