Pondering

These days I am wondering how and the heck I will ever wear another bathing suit.  Although I didn't get stretch marks or sagging skin I do have extra skin on my back and on my belly.  I feel like it is all around my belly area when I sit down.  I have tried on several bathing suits and get extremely disappointed.  I am very self conscious about it .  So I guess I am wondering will this ever go away on its own or will have I have to work very hard at reducing it.  I gained a total of 52lbs and I lost 32 really fast.  I have 20 more to go and it seems like its not going anywhere.  Do I diet, do I consider lipo-suction (lol jk) or do I need to do a million sit ups.  If you have any advice I would love to hear what you may have done to help your get back normal after having a baby or two!
