Struggling with Body After Baby

My son is nearly 10 months old and between poor eating habits and no exercising, my weight has blown up. I had great success losing weight before I got pregnant mainly with that as motivation. But I am just struggling to get back into it all again. I find myself being very depressed about my body image and it is taking a toll on my personal relationships as well. I know what I need to do, but it also feels so impossible between managing my job, home, and taking care of my son. My husband keeps telling me to do what I think I need to do to work on being happy again. It is hard when I feel out of place in my new body. I know this is common for a lot of new moms, but I am struggling.
