I understand. I'm in much the same place as you are right now. But as don't touch me said, there has to be a light at the end of the tunnel. However, the only way you're going to get there is if you seek the light. Walk through the tunnel is what I'm trying to say. There's a happier place there.

And as for your friends, if you really do feel a burden to them and you don't want to talk to them about it, you can always find new ones that care for you. It might take some time to find them, but just looking will help you find your way to a better tomorrow.

I hope everything gets better for you in the end.
