New Job w pigs Scared (advice)

I recently got a job at a petting zoo, I have a lot of farm experience, none with pigs. There are about 10 pigs, 2 huge ones at least 300+ lbs and a 8 smaller ones maybe 100 lbs.

I have to admit, the pigs terrify me. They don't attack, but they are strong. They live in a permanent pit of slop, like whipped mud, it's hard to maneuver in and they swarm around me trying to get things. If I give them anything they immediately destroy it and tear it apart like sharks in the water. I am so afraid I might fall into the slop and get hurt. Unfortunately, their water is in the peak of the slop (the other half of the pin is just wet mud and there is a somewhat dry dirt enclave no larger than 10x10). The water is constantly clogged because they shove mud in the float and you have to traverse the slop 1x a day to solve this problem.

I've never been so disgusted by animals in my life. Is there anything I can do? Advice? What can I wear to deal with this, muck boots to the knees are not cutting it. I am about to quit this job that is otherwise fine.
