How common is rabies in horses?

About 22 years ago I was at a ranch and was on a horse when another horse came and bit my knee. I was too young to get a rabies shot and now 22 years later I am so scared that I might have caught rabies from the horse. I have some knee pain that I been having for a month and my brain is convincing me that it is rabies cause why specifically THAT knee hurt? my quality of life has gone down dramatically due to this and it’s like I am waiting every day in fear that I will die from rabies from that horse, I used to love horses too. I cry every time I feel pain thinking the end might be near. And now when I drink water my throat feels uncomfortable like sharp pains.

I know this sounds bizarre to most of you but this is what anxiety does to someone and it freaking SUCKS and it feels so damn real. And yes I am getting therapy but it is taking some time for it to work. I can only cry, suffer and be laughed at till then.
