Insecurities

So I'm a single mother of my beautiful one year old Zaiden, and most of my life I've been insecure about my body and the way I look. And when I was pregnant I gained 70lbs so it got worse and worse, then my bf left me when I was pregnant and it was just like I ate every emotion possible. And now I'm 289 and I'm disgusted with my body. I have a tongue for a stomach, and stretch marks everywhere. And I work out and work out, but it's like nothing is happening. I know it doesn't just happen instantly, but it's like, most of the time I'll look at myself and lose all motivation I had to lose weight cuz I'm convinced that I'm never going to be the way I was. So please, what can I do to help motivate myself ladies?
