aww babu, don't worry about her. she is like a little spec in the air. while you, you are the beautiful sun in the sky, so bright, soft and many people love you. If I was with you I would help you, no matter what. Your teacher doesn't know how beautiful you are.
maybe calm down, the teacher is just a regular person, and why would you attempt suicide over one simple thing. To be honest you're Teacher has probably teaches for a long time, and he probably had to deal with a ton of kids, give him a brake. Well anyway hope that neck of your's get's well?
