Low labido

So I am recently married about a month and I have been on depo for 6 months, I got on depo back in April after a missed miscarriage, after the loss of the baby I developed a lot of self conscious issues with my body, feeling like it's completely failed my child and me. So as you can imagine I didnt have much of a labido to begin with (while I was pregnant we had sex all of the time, it was great) but no it's non existent, I don't think about sex and I don't get turned on, he has tried everything to get me in the mood but I just want him to stop touching me. Now mentally I want to have sex like I used to, I love my husband and I'm extremely attracted to him, he makes me blush still but physically I just cant get turned on and sometimes have to push past that comfort for him. I'm scared he'll start looking somewhere else, (I don't think he would but it's a fear) I just dont know what to do to get my amazing sex life back :(
