School is becoming a nightmare. Please help?

I have a hearing problem it is significant and mainly keeps me from hearing human voices clearly. High and low noises are much louder and often painful. I also have severe tinnitus (buzzing and ringing in my ears) that is exacerbated by spending time in noisey environments. I am in my 30s and in beauty school at a public votech. My hearing loss is relatively new. When I started school in January, I discussed it with my instructor, but he seems not to understand. There are some girls in the cl who my carpool partner says sit around and gossip about me right in front of me. They have been saying that I had a drug problem in my 20s but not to my face and they get away with this because I can't hear them doing it just inches away from me. They have spread this gossip to even my instructor and I think he believes it. It is so akward and I don't want to be the person always whining, so I've started to avoid cl, even though I am paying out of pocket while everyone else is on federal grants that I don't qualify for. I am trying to get help w/ my hearing but it is a slow process going through the testing. I also have high blood pressure and my medication has recently had to be adjusted due b/c my bp is very high and it exacerbates my tinnitus and it with my tinnitus I get frequent headaches. These girls whisper and cackle and the loud laughing hurts my hears. I was out today and my teacher said to my car pool ride that he hopes I am dropping out. He is so unfair. My car pool friend was out the other day and he gave her credit for the entire day by clocking her in and out. I was out for a doctor's appointment that day and I didn't get any credit. He says that I have to get a doctor's note to come back to school. I made an appointment w/ the psychologist at my doctor's clinic tomorrow. I have social anxiety and a fear of going back to school now. I need her to help me deal with my depression and anxiety and fears and to write a note that will get these absences excused and get me back on track. I am not really behind in my school work, in fact I was rather upset that I sat in that cl for the first 2 months but he didn't have anything for us to do b/c he did not yet have our texts or beauty kits. Please tell me what I need to do tomorrow in speaking w/ that counselor to get the help I need. Thanks!
