Need HELP with my weight :(

soo. i just had a baby girl 6 weeks ago and when i went into labor i was 169, now i am 137, but i have pretty much not been eating i guess for like the last week and i stay at 137, i even have been working out, and taking water pills and nothing is working, so, if anybody knows any diet or excercise or weight loss pill that actually works, please help. i'm trying to get back down to 115.
