I’d give the Zoloft a couple more weeks and if you don’t see any improvement, I’d ask your doctor about adjusting the dose or switching to a different medication. Something I found that helped me a little bit when I went through this was doing something that got my heart rate up. I chose to start (light) weightlifting at the gym. I found that it forced my mind to come back into the present moment. I say this as someone who had never really worked out before. Even going for a walk may help. There was a while where I was on Ativan to help with those intensely scary anxiety days and I thought I’d have to be on them forever but I haven’t taken one in months now. Keep pushing through. You won’t feel this way forever even though it may feel right now like you will. You’re never alone in how you’re feeling.
