I feel like I am getting addicted to cheese

I never used to eat cheese, well, atleast not the way I've been eating it lately.
I actually really want to be vegan, and I was, but recently I moved back to my mothers house, and ended up eating a piece of cheese and since then I cannot stop.
I tell myself.
Do.
Not.
Do this.

But. I always do.

I wish I had never eaten that piece of cheese, but honestly I don't know what to do
its just...
bad.
Its getting obsessive
I am thinking about the cheese all the time
