I've had anxiety for a few years now. But I've felt weirder today. Like I'm on the edge of a panic attack. It's been coming and going all day. I've just tried to ignore it to be honest but it's not doing anything. I'm on Citalopram which i have been forgetting to take recently but I've never suffered with panic attacks before. Does anyone know of good ways to deal with this? Can I just take an extra tablet?
