Would you give up if you had my body?

I'd focus on the achievements of having great health.

I say who cares about stretch marks....I have them on my boobs.....yuck....but I had my boobs reduced and now they are awesome...even with the stretch marks.....

1) How you look is only a part of losing weight. The benefits to your health are far more significant

I don't have kids, so I can't comment on stretchmarks from pregnancy, but I can vouch for the importance of having a strong core. Weight lifting, sensible amount of cardio, and compound exercises that also target your core (planks, deadlifts, Kbell swings) do wonders to improve your posture, they help improve your posture, and in the long run they reduce the probability of falling and breaking bones. Definitely do not give up on exercising!!!
Your skin will get better as you lose weight, and your stomach will shrink, but you will also become much healthier.

There's always going to be something discouraging. If I quit for every thing that won't or might not improve with weight loss, I'd have never gotten out of the gates. My stomach may never be perfect and I might always have stretch marks on my lady bits [oh yeah, those *kitten* got everything], but losing the weight will help with my back pain, breathing trouble, risk of diabetes, and the rate at which my muscular disease will progress. At the end of the day, the guaranteed benefits of doing something about it far outweigh the promise of nothing at all changing if I don't try.

What you see when you look in the mirror is normal. You are still beautiful, although it may be a different sort of beauty from the fake photoshopped beauty that is shoved down our throats. You are not a two-dimensional airbrushed image...but a real live WOMAN, who has lived and loved and given until it hurts. And your body is worth caring for.
I understand how you feel right now. I have had six children myself, and in a few short weeks, I will once again be doing damage assessment and tending to my battle scars. But I've learned that it is possible to look good and feel good about myself again, and I will just keep reminding myself of that. Time will fade those stretch marks into barely noticeable "tigress stripes". Feeding myself well with whole, healthy foods and doing some cardio will help melt away the cushioning that is sustaining the sweet little one and myself during this growing time. Picking up some heavy weights and doing some core exercises (planks!) will make those muscles not only strong but defined. After baby #6, I found that I felt stronger and more energetic than ever...and along with that, I was quite happy with my smokin' new body. You can feel that way about yourself, too, if you are willing to put in the time and effort to take care of yourself.
Never give up on yourself!

dont give up! you can tone and feel healthier. nothing will get rid of stretch marks its natural when you have had kids! mine are horrendous and trust me my tummy is far far worse you could tone a lot! my doc already told me id need a bloody tuck ouch. it really is not as bad as you are thinking, we are our own worst enemy! x

You know, I have view about life in general and when people try to reach their goals. I believe that whether you want to "give up" or not and you feel like your goal is too big to achieve you'll always be on your journey. If you don't exercise for a year, your still on your journey, if you eat like crap for a week, your still on your journey. They are just detours in that long road to your goals and its not a choice, its part of your life. You may not make the right choices or feel unmotivated sometimes but it doesn't change the fact that your still growing and learning your whole life and thats unstoppable no matter how hard you try to fight it... Its all part of the process.

So when I see "should I just give up because my body looks like this"? Its a big Hellz no! The stretch marks will fade, the skin will tighten, the fat will vanish and the muscles will grow if you put the work in. If you don't, well, its just postpone for a later time.
Giving up is not an option.
