How can I lose between 35 and and 56 pounds by May?

I weigh 115 pounds, (this is NOT a typo), am just under 61 inches, and I am 19 years old. My stomach, thighs and are WAY to fat, people always said 'go away fattie' or 'go away fat woman' to me at school before I graduated, and people send me messages on facebook saying to lose this much weight and say I am a fat woman. I also need to lose this weight so I can wear bikinis every summer. I drink 1 soda a week, eat ALL junk food in moderation, drink tea each day, work out, but nothing seems to work for some reason. Can SOMEONE please help me find ways to lose this much weight?
