Anxiety Attack

I woke up with difficulty breathing and a bit of a panic attack. I tried to sit still and take deep breaths but couldn't stay still at all. Eating some snacks helped, as the act of chewing helps distract me I think. I used to dismiss people who say they get these anxiety attacks, thinking they are such drama queens, and now I get them myself. Not sure if I should attribute this to my current diet (too much caffeine?), my life experiences leading me to this, or what. I had a 4 day long weekend and am well rested. So it shouldn't be caused by stress. I wonder if this is the effect of aging, and I will just keep accumulating more of these small annoyances as I get older. What's next, random pain in various parts of the body, and hallucinations? I am already quite forgetful. Maybe dementia is next.
