The metaphors in here are great and really emphasise that dark emotion going on, the inner pain and depression.
I love this line:
My love for you is grey mist on
Friday the 13th, as I try to cut
out nocuous thoughts of you from
underneath piqued skin.
- the idea of "cutting nocuous thoughts" from skin is amazing, so unique and gripping!
I also like how you use white as a colour for love, instead of the usual red or pink. I think the ending is so contrasting, a white love but yet such a dark world that you never felt able to understand or belong in.
