What can I do to make myself not so insecure?

I really just need to feel myself again, and genuinely love myself. Ever since I had my son I have not felt pretty or skinny. I gained 70 pounds when I was pregnant, and it really took a toll on my body. Of course it was 10 months ago and I’ve lost a lot of the baby weight I’m still almost 25 pounds over weight still and I’m a stay at home mom and I feel like I’m never doing anything for myself.. are there anything that has made you guys feel better about yourself?
