Why me?

Funny thing is they only try and tear me down when i'm happy.
When i'm not happy, they act as if they care, which brings me down as well.
Noone can tell me that they care about me and love me. Got it? You can all say they just do it out of love, well thats not true.
You havent lived with them your whole life, i know why they do it.
So dont you tell me they love me, don't tell me they care.
