How Can You Find Yourself When Your True Self Has Been Robbed Away From You?

After almost 10 years of domestic violence, and 2 more years to realize I've been a victim of it and get my ex out of my life for good, I don't know who I am and what I like anymore. Like most narcissist perverts, my abuser has taken away all my talents, my intelligence, what made me who I am. Now that I am married to someone who treats me right, many people say that at 29 I'm young enough to go back to school to have a job I like. Or that if I insist on staying in executive jobs, at least find a hobby I like. But how do you do that when you don't know what you like and who you are anymore? Yes, I can think of what I used to like when I was 17 and younger, but I'm no longer that age and that person anymore.
