Looking for advice on adding medication to improve anxiety

I’ve been on sertraline almost two years now. It’s the med that’s helped my depression the most. I still get depressed but not as often. But my health anxiety is severe. I take klonopin but don’t want to take it everyday. I won’t come off sertraline unless it completely stopped working. I switched from Paxil to sertraline and it was the worst time of my life. The depression was unbearable. Anyone add a med and anxiety improved? I’ve already tried buspar. Made me depressed.
