I know how you feel. I've been through it before.
I'm still dealing with it right now, too.
There are friends out there, who want to help. I know I have some. Someone loves you, even though you have no idea where, or who it is.
So, just make sure to never give up. Fall down 7 times get up 8.
I wish you luck, because in the end, I know happiness will come to you, and me.
