Hi, I've been taking 25mg of Zoloft for 4 days now, for panic attacks. I'm afraid of getting insomnia. So I take it in the morning, and I'm exhausted all day. I have been crying non stop all day. Before I took the Zoloft I never really got sad. Just panic attacks. I'm confused, if I'm taking an antidepressant then why would it send me into a depression? Any ideas? When will the good feelings kick in? I'm so sad.....
