I'm 17 and today all of a sudden I felt panicy, I felt tense, my stomach felt sick my shoulders and arms before heavy and tense and I had trouble taking a big deep breath. I thought it was anxiety so I tried to calm myself down by telling myself I would be okay I just need to relax. Tht didn't help. I layed down on my bed and just closed my eyes and tried to slow down. That didn't work. I still have it now. It's been 10 minutes. Does anyone know if this am anxiety attack or not? I'm really scared and don't know what to do
