This is therapeutic! Thank you so much for you replies.
I'm going to check about PCOS (I'm scared now ... nevertheless, I should go on and see if I have any such problem ... )
I know I'm not obese or unhealthy. It's just that my weight lies in my hips & thighs. So it's very unflattering.

I wouldn't care if I weighed this much as long as my weight ws evenly distributed you know.
I don't know why I can't stick to diets though. Well, what I mean is, stick to a proper routine-based diet. I do for a few days and then go back to unhealthy habits.
