Embarrassing Question

So I was on the depo shot for a month for the people that don't know a side effect is lose of sexual desire. At first I still had sexual desire but now I'm not able to get turned on anymore, what used to work (masturbation, porn, reading smit) didnt work. I've heard that if you don't eat a lot of meat you're sex drive is supposed to be higher, I'm already a vegetarian and it got worse. I used to get turned on by almost everything but now I don't get turned on at all. What's wrong with me? How can I get my sex drive back?
