How do I deal with this phobia/anxiety?

Okay, so I am going into grade 12 and I have encountered a problem. Long story short, I have to take biology all year, which I am terrified for. Plants dont bother me much, cells dont nerve me either, but I have this really embarassing fear of what is inside the human body, that nobody seems to understand. I looked it up on the internet but there are almost no results.....

Like every time i am in a public place and think about it I nearly get a panic attack and that feeling i got to escape or else .....

Anyways, I think this phobia really connects to my anxiety. I have had anxiety issues since I was 10 years old and my parents never understood me, they were all like "grow up!!!" I am on anxiety meds, and they help but i still get nervous, especially about the human body..... But it is weird, sitting here in my bedroom right now, because when I think about some organs, it does not bother me too much. I do not feel lightheaded, but if i am in a public place such as the mall and i think about this I feel lightheaded and faint.... Which connects to my other phobia, my fear of fainting, which I also find embaressing which is why I am writing about this anonymously on the internet because here, I dont feel as though people are judging me that much.

What should I do to help with this problem? Am I the only one here?

I would make sure to tell the doctor who prescribed the anxiety medication this particular problem and how it is going to affect you this year at school.

I would also confide in the teacher you are to have for this subject.

Exposure helps to relieve anxiety. You can resolve to commit to this class and ask the teacher to work with you to help you successfully get through the school year.

Confide in your parents. They deserve a chance to comfort you. If they cannot comfort you, they still need to know because they are legally responsible for you. Courage! You can do this.

I have fainted and as you can see, I woke back up. I can look back on my younger self and realize now that I was among a lot of other younger people; all of us trying to grow up and find our way. They can empathize with you if you faint. Anyone who would make fun of you is a sad soul who needs the teacher to instruct and correct them and you to pity them. Courage!
