Okay here is my take. I think its about self harm as a habit, which has been passed on to a friend.
I see through her - She knows what its like
Poisin that runs through her - Maybe just about the feelings that you have to be going through to self harm.
Kill me faster - Its not very easy to die from cutting yourself unless you purposfully go for the veins.
some things you just give away - the habit
The rest is self explanatory
