cannot lose weight!

I'm 3 months PP 2nd Csection. Since then, I've been on a low carb diet, +exercise, drinking ONLY water and coffee in the morning... I have only lost ONE pound... I'm so upset. I am on an antidepressant that makes it very hard to lose weight. I hate the thought of taking diet pills, but I can't help but consider it. I have anxiety and high blood pressure so the ones with stimulants are a no for me. Anyone have any recommendations? I'm actually very depressed about my weight. Before my first I weighed 120. I now weigh 160, and cannot lose this 40lbs. Nothing fits me anymore, my body is so disproportionate, my legs are so skinny but my abdomen, face back and arms are so big. I hate it 😞
