I'm deleting my Youtube channel

Here's the deal. I have a YouTube channel with videos, some of which you have seen (i've posted them on here) but some people who I know personally have been bull-shiting and calling me names on it regally. I am sick of this. I have seriously been thinking of killing my self like some of the comments have told me to do. Example of this crap are Here:

So I am making all my videos private, if this doesn't stop, I will be deleting them. I am leaving one of the videos open though just incase. With lots of hope for... well.... my life...
