I'm sorry I missed you, please don't hurt yourself. I know how you feel, I feel that way all the time. I feel broken and defective and unfixable, and I care about people so much but they don't care if they ever see me again.
I had a friend that had a hard break-up, and it hurt her for over a year too, but she eventually got through it, and so can you. You just need help. If you come back we can talk about it. I don't know how much advise I can give, but I promise to listen to everything you want to say and help any way I can.
Please just come back and we can talk...
