Spicing it up!! HELP!!

So I've been married for almost 7 years and we've got 1 amazing daughter (she's 3 years old), through the chaos my hubby and I have grown appart. I've been trying to think of ways to spice up our marriage, especially the sex. I don't know what to do!! I've read that its sexy that the woman "takes charge" but I have so so so much negative body issues. I am so self conscious because I am not as pretty as I used to be. I've gained weight, always tired, and I am depressed. But I really want to make my marraige work. What can I do?? HELP!!!

Me and my daughter ❤😊
