This part is particularly difficult for me:

|----------------| (not aligned very well, but it's the fast part repeated 12 times)

Can anyone give me any advice how to play this faster? I can do it at a much slower speed. I'd like some explanations, please..

Thank you.
I know exactly what I think I'm doing.
bar the 13th fret and form a chord kinda if u know what i mean.

well, one thing to make sure you do, is never take your index finger off of the 13th fret. just keep it anchored there and alternate bending and pulling off and then hitting that 14th fret on the G string. other than that, it's just practice. keep practicing it until you get it right.
