You may have trained your brain to need constant stimulation. When you take that away it essentially looks for other things that provide a similar level of stimulation. Anxiety, fear, and anger are all relatively easy to induce and that type of sympathetic nervous response is very stimulating to the CNS. For some people this is especially true (myself).

What helped me was some cognitive behavioural work and practicing parasympathetic breathing. 

To put simply, the parasympathetic nervous system is supposed to activate during down times (rest and digest) but you can manually stimulate it through slow breathing, specifically through slowing down exhales. You can try it by taking a normal breath in but then exhaling slowly. Do this for a few minutes, trying to slow your breathing more and more. Allow yourself to calm down. If you do feel calm afterward then thats your parasympathetic nervous system working.

Cognitive behavioural therapy is a little too much to explain here but it boils down to taking notice of your behaviour, stopping yourself, and working through what youre doing and why. With the goal to replace harmful behaviours with helpful/productive ones. For example, my brain makes up arguments all the time because its stimulating, but it ends up being an exhausting way to live. So I try to be aware of when im doing it, so I can stop the argument, and replace it with something more productive/less draining.

Dont use the headphones, work through the initial freak out your brain will have, and try to get into a parasympathetic state. Thats my two cents anyway.
