Having stress diarrhea and every single day

I have bad anxiety and at my new job I’m pretty much bullied every day. I get so nervous and stressed out that I’ll poop right before I leave hut as soon as I get to the building I’ll be running to the bathroom. I want to get some medication but I need some now and don’t know how long I can set aside time for therapy until I can get some medications. I can’t switch jobs because I’m getting paid more than I ever have and it’s a good opportunity and I’m trying to hang in there until things change for the better. Any advice on what to do for my nerves?
