Searching for some answers.

I'm a sex addict who posted on the website many times, just strictly about my sexual issues, until know. if you ever read some of my past post you would have seen that I attended therapy sessions. well up until recently I had discovered that my therapist had died unexpectedly, which left me not only in limbo but with quite an empty feeling. to be frank hearing the news of my therapist's passing had left me kinda ###$ up. it has gotten to a point that my depression has come back full force and I cant shake it. ive been taking Prozac for a year and some change, but my wife fears that its not enough to bring me back. the depression is staring to seep into my professional life also. granted ive had issues at my job, but now recently im at a point I honestly don't care anymore about the job I have. at home its just the same, my anger is starting to build up to the point I fly off the handle sometime. ive truly became a miserable ###$. I trace it back to my therapy sessions. I was in a good place with my therapy to the point I looked forward to going. now I feel that its unfinished business. the last conversation I had with my therapist was that I need to overall figure out what I need to do with my life cause I feel like im floating aimlessly watching life pass me by. I feel cheated cause I was searching for some sort of answers. now I have to start all over with another therapist back at square one.
