Poison's Effect

I'm back from the camp finally! There were some good and bad memories, the bad ones are kinda stupid, but the good memories keep my mind off of the stress I've been having. My friend finally is talking to me again, I don't know still what caused that, but I'm really happy about it. Well let me see, what shall I write about? Here we go....

You are finally past it,
You know you won't go back,
but then you are lured there,
with all the defences you lack,
you get traped again,
and the poison seeps in,
you don't notice it happening,
you think you're going to win,
but then it happens,
the pain you fought before,
you wan't to escape it,
the one you adore,
it burns inside,
makes you not sleep,
you get shivers inside,
it is very deep,
when it is finally over,
the poison still inside,
you go back to your home,
and you will try to hide,
but you might get drawn back,
for another poison's effect,
but maybe you will learn,
how to beat this effect....
