My co-worker "requested" a fursuit head....

It's a zombie cat and he gave me a really complicated drawing and wants perfect to that
I'm like

Well
I have known style I already made him one but he didn't like it and I'm like

Um
Okay but your buying the materials
So he agreed to that and he got the worst fur and shitty glue sticks and disgusting foam not the kind i asked for and I'm like why
I have no motivation for this project, he's stressing me out like crazy, and I'm literally sitting here looking at this piece of shit i have to do he originally "requested " the first one and I asked him "well aren't you going to pay me" and he's like "well I heard your a furry and I dont know what your work looks like so why should I pay you, you're not worth my money." And I just stood there and took it because I know this asshole in real life and I have to work with him, he's my co-worker and I come home two out of three days that he's there in tears because every time I see him he asks " HOW GOES THE MASK NOW GOES THE MASK NOW GOES THE MASK" and I just say "good" really quietly and walk away it's like I can't escape him and I cant go to management because he would bully me more and it would make things akward and it's gotten so bad that I've started cutting again and I just want him to leave me alone but I just can't escape and I just want him to stop.
