Concerning Merry...

Meriadoc had a great life with the two people he loved the most: Peregrin Took and his father. 'Dad-dad' as a child, 'daddy' when he feels mischevious, 'father' when he has done something bad, and 'Pops' at any other time. He loved his father. He loved him so much.
and Pippin.
Pippin was his 'best best best friend in the whole wide world' since as far as he can remember. They grew up together, ate together, swam together in the lakes surrounding the Shire, played together, and even lay down together underneath the huge willow tree in Pippin's garden.
That willow tree was one of the most important things in his, or Pippins life.
His mother died when he was 11, very young for a Hobbit. She died during teh Red Plague. His father and Merry were able to battle this terrible illness, but she couldn't. She was always so frail and fragile. But Merry didn't cry at her simple Hobbit-funeral. He just bowed his head and held his Dad's hand very very tightly. He knew his 'Dad-dad' needed Merry as badly and Merry needed him.
When his father had left this world for immortality, it was the first time he ever cried. Pippin was the emotional one...but it was different this time. Instead of Pippin crying because he fell down and hurt his knee, it was Merry who was weeping on Pippins shoulder.
The other time he cried was because of Gandalf's fall, and...because of another event.
Pippin was the world to him after that. Everything was Pippin. Pippin was his main priority. He needed Pippin so badly, and he would only tell anything important to Pippin. Pippin, Pippin, Pippin. The name that was his only saviour.
He would die for Pippin.
He would die without Pippin.
