I have been taking Zoloft for approx. 5 weeks. I noticed a big change and now I am experiencing racing thoughts again and physical symptoms of anxiety have come back. It started pretty much exactly a week ago, my partner left 5 days ago to go back to work but it started before he left. I also think I am getting my period soon and that usually makes me anxiety worse but its depressing because it was going so well and now I just feel like I used too. I started on 25mg now I am up to 100mg sometimes 150-200mg depending on the day
