My teacher is ignoring me and I'm not allowed in her class. Please help!!?

So last Wednsday she called me out in class and I said what I did was the pure definiton of insanity. A boy passes me a note and basically called her insane cause she was on the tyra show because she ate chalk and COMET(cleaning supply) while pregnant. And we later found out the baby died. I didn't mean it was just mad. Then I was on facebook and posted a status about what happened. I was commenting with a friend and said I hated her. She commented and said she wanted nothing to do with me. I didn't mean it. I was put in iss because of the note for 2 days. I have to go back to class tomorrow and I'm not allowed in her class. I appologized to her 3 times on facebook and I wrote her a note. I tried to talk to her in person but she complety ignored me. When I tried to turn in an assignment she wouldn't even open the door so I had to slide it under the door. I don't know what to do she hates me. I can't even go to class tomorrow. What should I do? How do I get her to forgive me?
