How to overcome feeling emotionally numb?

Up until a few months ago I was seeing a guy from another town a few hours away for almost 3 years. We tried living in each others cities and it never worked out. But anyway, about 4 months into the relationship I had a traumatic emotional experience. He was very supportive at first, but then after a day or two blew up on me, was very mean and told me to stop talking about it. Ever since then I’ve kinda had this empty feeling inside that had lasted the majority of the relationship. He was a very controlling and manipulative person. I don’t know how to overcome these feelings. I’ve started seeing someone new since then and he’s an incredible guy, but I still have trouble being intimate and feeling enjoyment from it. I have tried depression and anxiety medications… didn’t help. I am following a mostly vegan diet, had blood work done and the only thing I was low in was vitamin d. If anyone could offer any sort of advice or has experienced something similar, a response would be very much appreciated.
