Does Sertraline help with rumination? Help

has Sertraline helped with Rumination?
Ive been having constant guilt about tvings that have happened years ago since having a breakdown 2 months ago

im on 50mg sertraline for over 4 weeks and Im really struggling

Hi, I have taken sertraline for 12 weeks. I was having lots of negative thoughts but they have almost completely stopped. Unfortunately I am experiencing a tremor since increasing my dose to 100mg. Waiting to discuss with my psychiatrist.
