I NEED HELP!!!

Hehe! Okay so I am looking for this Harry Potter story and I need your help to find it.

The story is Harry/Draco pairing.

And Harry and Draco are twins and…. elves, I think. But they were separated at birth. It starts at their like seventeenth birthday and Draco is hurting cause in this story when elf twins are not together they are like very depressed and physically hurting.

I remember then they find harry and take him home. Voldemort is good and Harry can't stand to be touched by anyone but Draco. Then they find out that Harry was kidnapped by James or Lily or Remus or Sirius, can't remember which one kidnapped him. I think it had thirteen chapters.

It would be a huge help if you could tell me the title and author of any story that remotely sounds like this.

Thank You!!!
