Can anxiety and panic attacks be treated with psychiatric therapy alone?

Hello doctor,

I am currently experiencing severe anxiety and panic attacks. I am naturally a very happy and outgoing person. I have been hit with this massive wave of anxiety every day for the last three months. I have never experienced anxiety before this. I have been to get testing done, and my doctor said everything was fine, but I was deficient in vitamin D. I am not worried about anything in my life. I am convinced it is health-related. It is affecting my everyday life, including work. I have seen a psychologist and felt nothing had helped my everyday panic attacks. I have been on several medications and now have been prescribed Oxazepam. I do not want to be on medication; I want to return to my old self. Kindly suggest.
