I'm 17 and I take 50mg of Zoloft for anxiety and depression. Here recently I've been dizzy and lightheaded and I think my medication is causing it. Should I tell my doctor about my new symptoms? I told my mom and she got kinda annoyed because she doesn't want my medication to change, it was a huge hassle to get medication in the first place. I've been taking it for over a year, this symptom is fairly new, and I'm worried. If anyone else has had this experience, please do share. Thanks.
