I agree with the above posts. You might just need a higer dose. Please check with your phyciatrist first.
JGF25 is right. Remember you will get better again. If you cannot get to your doctor very soon, perhaps you could call a pharmacist and tell him/her about these symptoms. I have found pharmacists to be very wise. My best to you!
I agree with the above poster. Perhaps the stress in your life has gotten worse and the previous dosage of sertraline is no longer working for you. You may want to explore an increase or a new medication altogether with your psychiatrist. The important thing to remember is that you have been able to get better in the past and you will get better again, you just need a bit more help right now. Best wishes...
My heart goes out to you. You really should see your doctor about these problems. Would that be possible for you? You may need to switch to a different medication.
