For the past 3 to 4 days I have been experiencing increased anxiety and irritability. I've also had some trouble sleeping, even when taking a sleep aid. Today my anxiety skyrocketed for no apparent reason and I've been quick to anger and irritable. I also started having neck, upper back and jaw pain (just feels tense and uncomfortable) the neck tension is the worst. I've been easy to get hot and have a headache. And now I can feel heart palpitations and startle easily. 

I want to note I am on Adderall, only 10mg BID. I never experience physical symptoms of the stimulant unless I don't take it with a meal, and it actually improves my irritability. I've been on this dose for over a month and never had issues before. 

I'm wondering though if maybe these symptoms see side effects just now showing up for some reason or if maybe I am experiencing an anxiety attack. I've been stressed lately due to my career (it is extremely high stress, working at a hospital), and not really being able to relax when I come home due to a child in the home who is very loud and hyperverbal. 

This is the worst I've ever felt. I've never experienced such severe anxiety ever before.
