Lack of Confidence

I need help y’all I feel so down about myself lately. So I had a baby 6 1/2 months ago(my third), i didn’t gain a pound but I have the extra flabby skin and pouch. But most of all my face is still chunky. What can I do to help with my chunky face? I eat super healthy, I don’t do much working out but I take 20-45min walks twice a day sometimes more (depends on this upstate NY weather). It’s not ppd I’m a happy person and have no bad thoughts, it’s only my confidence is low.
