2 months pp & weight

I'm 2 months pp, my pre pregnancy weight was 145 lbs I'm 4'11 and I used to weight 115 lbs then got on depo and gained weight and was at 145lbs now at 2 months I'm 156 lbs. I'm struggling with sticking to workout out and eating healthy. I want to fit back into my jeans so badly but I'm stuck on where to begin with weight loss. My goal weight is 130lbs. What's the best way to loose weight? Does thrive help? Does anyone have samples I can try out before making a big purchase. I'm desperate! I feel so horrible about my body and want to be healthy.
