girl, you need to chill out!! dont get into a frazzle over it! youve had babies before, and im sure the weight dropped off then too, especially if you've kept yourself healthy and fit all the while. its easier to bounce back when you've been healthy all along.
however, either way, after having 2 pregnancies, its going to get harder.. your skin and stuff will probably not get back to 'normal' - it shouldnt. thats normal. just do your best, dont stress about it, eat more fruits, legumes and vegetables and whole grains, LESS dairy, meat, etc.... thats a guaranteed healthy choice. more water. what else... more fiber! :D
what you need to do is not worry so much about fitting back into your old clothes. the best advice i was ever given after having my son was that i may never fit back into the clothes i wore before being pregnant, and THATS OK.
it gives you an excuse to go on a shopping spree (hopefully kid free) and buy new ones. nothing you have will fit you the same way even if you get back down and fit into them. they wont fit the same. your body has been through tremendous change. this is all normal, and OK! :D
you have toooo many pants anyway. my rule of thumb is to never have more pants than i can wear in a week, including a night out or something. ive NEVER had more than 7 pairs of pants, including sweatpants or workout pants. (however, this is NOT by choice. i just cant see the sense in having that many clothes to wash, and i cant afford to buy that many pairs of pants...)
the best thing you can do for yourself is go somewhere and get pants that fit you great NOW, not in the future, and donate the rest of the pants, or a majority of them, to someone else in need, or a thrift shop. when you lose more weight, go out and buy another pair or 2.... gradually you know? this isnt about completely replacing your wardrobe, cuz you dont want to buy 50 more pairs of pants and then not fit into THEM in a few months.
just accept that your body isnt the same, and get pants that fit your body now! :D not later.
ANOTHER GREAT THING TO NOTE: you dont say if you are nursing or not. i lost the initial weight breastfeeding, and around the 8 month mark, i lost 10 more pounds. around 14 months (i nursed for 19 months) i lost another 6 pounds. breastfeeding is a guaranteed way to lose weight.
anyway, the biggest thing is to NOT stress out, DONT eat lots of meat or dairy, drink lots of water, and allow yourself a treat now and then, whether its one piece of chocolate once a day, or a special dessert once a week, whatever. its ok to have ice cream, just have only one spoonful or one scoop!
