I've been on sertraline for coming up to 7 weeks but if anything my anxiety is worse. I've recently increased to 150mg, but I've been on 100mg + for about 3 weeks before that. I'm despairing of it ever working. I had a good day on Christmas eve but then got flu on Christmas day and have been experiencing terrible anxiety since then. I'm not really eating as I have a constant knot in my stomach. I feel scared to go anywhere and need someone to be with me. I have thoughts if ending it all but would never carry this out, I just want it to end. Does anyone have a similar experience? All the threads I read say people feel better after about 4 weeks..
