How to treat low libido in young women?

I am 19 and have recently started suffering from low libido. I am in a relationship and have lost all sexual desire. I know its not my partner but I don't want sex and don't enjoy it. I am wondering if there is anything I can do or take to help me? It is seriously effecting my relationship, I feel like it's never going to work when I feel like this but I don't want to lose what I have. Any help would be appreciated, thankyou so much
