Low sex drive

So about 2 1/2 years ago i got out of a sexually abusive relationship.. And I've been with an amazing guy now for almost 2 years. I haven't had a normal sex drive in a long time.... I want to have a sexual relationship with my to be husband but i don't know how to get myself back into wanting sex... I love the idea of sex but my last relationship really damaged me. Dose any one have any advice on how i could get a higher sex drive? I'm on the IUD and i was on Depo for 2 years before switching a few months ago.... Please help.. I want to feel like the 18 year old i am.
