Nobody at work likes me and i had a accident?

My mom says I should stay at my job but I say otherwisae. I'm 17 and I work at a golf course. i've been there for 8 months now. My job is only good for a year and then I'm done. I have 4 months until my job ends. I got hit in the balls while picking ball out of the ditch. We had to pick balls out because of maintenance cutting the lawn today. So it was manadtory that we did this. yesterday by a golf ball and it hurt like crazy. I mean the chances of it happening are crazy like 1 in 8000. The girl didn't mean to hit me and she didn't even say sorry or help me up she just laughed. My co worker was laughing too. I mean it wasn't funny to me becuase I was in a lot of pain. I allmost passed out because of it. The only reason I've stuck around so long is because i needed a job for my co op class. This was the only job that called me and it was take this or get dropped. Now that summers here im just doing this job to make spare money. I told myself when I started and if I ever got hitby a golf ball or stung by a yellow jacket, bee, wasp or red hornet, I'd quit. Also everyone talks about me behind my back because they think I'm stupid, but I'm not. This is one reason I cant stand them because there like twice my age and all they have to do is to make fun of someone younger than them. Occasionally if they do something wrong i'll tell them because i get blamed for everything becasue im the youngest worker there. I just do things differently and get the job done a lot faster. I'm thinking on putting in my two weeks notice and leaving after I get this last paycheck. I didn't save a lot of money but I put back some money. The school years over now and I won't need the job in anymore. I only have 4 months left and I can use that time to find me a new job.
