I weighed myself a couple weeks ago and the scale said 153.. then I got up and weighed myself this morning and the scale said 164.5!

My highest weight used to be 140.. well I definitely broke that record. I weigh myself at the same time each day so I know the scale has to be right... sadly. I haven't noticed my clothes getting any tighter or anything though! I'm a 16 year old girl and my height is about 5'4 ish the last time I was measured. What is a healthy weight range? I'm also on the anti-depressant Zoloft, has anyone else been able to lose weight easily while on it? I heard that if you are on any anti-depressants you will never lose weight because it slows everything down.. is that true? Well thanks everyone!!
