I got severally depressed while pregnant and ended up on anti depressants. They worked wonders and I've been taking them ever since. They make me function normally and I've been able to really enjoy my life. Now suddenly I've started to feel like I'm at the top of a roller coaster waiting for it to drop. I constantly feel like everyone is talking about me or annoyed with me. It's totally out of the blue and I'm worried my medicine has stopped working. I do not feel even a quarter of how I've felt in the 8 years before starting medication, but I'm so scared. I just can't go back to having anxiety and depression. Has this happened to anyone else? Can meds stop working?
