I struggle with anxiety and depression, but recently it's gotten way worse. The past week, I've had the worst panic attacks ever which seem to last for hours. It's the normal symptons; head burning, shaking, nauseous, tight chested and all that. But it's made my heartbeat really fast and I've been experiencing weird feelings in my heart like flutters but really scary like it's going wrong, like my heart is stopping or something. It terrifies me and triggers another panic attack and everything. The thing is, it's alright during the day when I can sit and tey and calm myself vut when I lie down I vet the weird flutters/palpitations and feeling like its really fast like too fast. I'm really terrified that it's something more than anxiety because the physical aspect of it is SO real and scary. I'm 18 but quite unfit (spend most of my time inside doing nothing, not eating very healthily) and I dont know if that has something to do with it. But I'm juat terrified that something's horribly wrong but am scares to go to the doctors bur at times think I need an ambulance. Does this sound like anxiety or something more serious??
