FRIENDSHIP

Friends...
What's the meaning behind these 7 letters?
Can anyone pls explain this particular word to me?
I somewhat feel really lost about it...
Are there really true friends that we can lean on?
That we can really trust?
That we can really hook on?
Friendships...
Another difficult word...
What's a friendship?
Is it necessary to have it?
Can we have faith in a friendship?
Can we cherish it?
Will the boat of friendship sink?
If so, can we prevent it from sinking?
If yes, how to do it?
Does anyone out there could give me an answer for each question asked?

ps: I'm a little confused...so...sorry for being so emo...
Anyway, comments are always welcome! =)
