For about a month, I was on 50mg of Zoloft for major depression/severe anxiety, and mood swings. I felt the best I have in, gosh, four years. but I still had a small bit of anxiety (manageable) and I didnt think increasing my dose would be harmful. Two weeks ago, my psychiatrist increased the dose to 100mg. Since then, I have been extremely anxious, felt like crying, and its causing a big strain in my relationship with my boyfriend and I feel absolutely horrible. I dont even want to continue to take it at this dosage, but I don't want to go back to how I was before I started Zoloft. Until I can see my psychiatrist to lower the dosage back, what should I do? I really dont want to keep taking it. I feel horrible. Also, I've read that children under 18 shouldnt take Zoloft, and studies have only shown improvement with children diagnosed with OCD. I'm 16, could that have anything to due with the severity of the side effects? Like I said, 50mg was great, but god I feel horrible now on 100mg. Please help !!
