What works?

I’ve been in a depressive state up until last month and I’m so worried that they’ll come back. I came started a new job this Monday (I was performing poorly at my last one and I got poached-for some reason- by this job, so I didn’t get time to be on any PIP at the last job.) I keep failing up and I know it won’t last forever. I’ve been consistent with therapy, I workout almost daily, I’m taking vitamin supplements and I’m on 200mg sertraline and 100mg queitipine. I don’t want to lose this job. What has worked for you?
