Hey! I know what you feel like. I use to weigh 170lbs and now I'm 147. I went from a womens size 18 to a Juniors size 13. I still have a little way to go because i want to be about 135lbs. I'm also 5ft 1inch. The things i did that may help you were 1) count calories, first, eat regular for a day then figure out how many calories you ate. Then, if you want to lose a pound a week just by cutting calories, cut 500 calories and day. So if you ate 2200 calories regular, cut it to about 1650 calories. 2)Also, I know from personal expirience that it is harder to excercise when your heavier. Well start easy and work your way up in difficulty. I suggest to run in place for 1 minute each day for 1 week. The next week 2 minutes a day. Then 3 minutes a day. All the way up to 10-15 minutes a day. This will boost your metabolism and make u look and feel better. Don't forget to stretch before, though. You'll be less sore the next day. Do this religiously and within a month, you should loose 5-10lbs. I wish you the best.
