I am 21 and suffered with anxiety for 5 years. I have been on sertraline nearly 4 weeks and I started on 25mg for 5 days then went onto 50mg after 3 weeks. I did not feel any better so I was then put on 100mg. Ihave been on this a few days and I just feel I am getting much worse and my anxiety is through the roof. Is this normal? When will this settle? Will my anxiety ever go?
