I'm falling for my teacher! Please help!

I'm 16 and i'm a junior in high school. I have recently developed a hardcore crush on my dance teacher. She's beautiful, funny, sweet, smart and has a wonderful personality. I wake up every morning only looking forward to see her. I think i'm falling in love with her. I find myself always trying extra hard to get her attention. For example, I went through depression for a year (which she knows about), and now I am on meds for them and am doing a lot better. But one time, I purposely skipped my medication that day, hoping I would have a huge meltdown in front of her so that she could comfort me and maybe even hug me. I didn't break down in front of her like I had planned, but its still a crazy, desperate move to get one's attention. (I'm not the type of person who has to have attention all the time, I just really like her a lot.) I've dreamt about her quite a few times. Like in one dream, she was crying and I was hugging her and telling her that it's okay. I instantly knew that I had that dream because I am strongly craving her touch and comfort. At times, I just enjoy this crush the most I possibly can, but at other times, I get really emotional about it because I know I can't have her. I am getting very bothered by this because this is an everyday thing. She is the only thing I look forward to everyday, and I only see her for 50 minutes. This is very confusing and contradicting. I love when I talk to her because she keeps straight eye contact and her eyes are so beautiful and hypnotizing. I really need help with this situation. What do I do?
