It All Builds Up, It All Falls Down (Age 15)

About a friend who constantly used me.

Why can't you stop, or haven't you crippled me enough?
I'm sorry, man, but that's the same s**t, the same stuff
That you expect me to accept like it's true, like it's you,
But I reject it, I detect it's not truth, and don't ever say it is
Because I know you better than this. You think that maybe
I won't go crazy if you tell me it's alright, because you just
Think I'll see the light, but you are soon in for a huge fright,
Because I might just decide to not take it anymore, don't you
Act like you did not know the score, what do you take me for?
I'm now like a child's precariously positioned building blocks,
Don't come back crawling on all fours, I'm not answering your
Calls, and don't tip me or I'll fall, you spent all these years,
Waded through all my tears, building up the tension I feel,
But do not heel, do not kneel before me like a helpless creature,
I don't know you anymore, have taken all I can, and now I'm a man,
I'm older and bolder, so you can't control me like a puppet,
Growing colder with every minute I see you, the true you,
Who has no clue of how it really might feel to take all your s**t.
I'll have none of it, and on you I spit, the one person I once
Thought of as a friend, pushing me until I have to just quit.
