To put an end it to.

You reassured me you're a goner. And that you deserve no help since you cannot repay the kindness of others.  

So disappointed in you. Always have, and always will (you just proved me right today). 

I have nothing else to say anymore. This is the last time I'll post about you because you're just not worth my time. All you want is just to take, never to give. Wow, what a harsh and horrible world it is with you in it. I'll just wash you out of my system, out of my life. 

Taking out the poison....
