Zoloft

I started taking 25mg off Zoloft a day for OCD/anxiety about a week ago. I felt AMAZING the first 2 days. It was everything I wanted it to be and I had no side effects. Now I’m super tired no matter how long I sleep. I also feel a bit depressed, and I wasn’t depressed at all before. I just want to know if anyone has any experience with Zoloft. Will I ever feel energetic again?
