Hello,
Your symptoms are reflective of painc disorder and they seem to be quite broad in settings- from home to cars and assembles etc..making you rather incapacitated.
All of this reflects the increasing severity. You dont want to see a
psychiatrist, so I will try to help you with some tips but if they dont work enough for you or the illness seem to worsen, then you should visit a psyhiatrist-- for your well being!
Tips-
-go for brisk walks 30-45min daily
-practice deep breathing technique of relaxation- JPMR and do it daily( you will easily find its video on net)
-shun the habbit of having tea/ coffee to zero or bare minimum
- avoid any drink containing coke/ taurine/ tannin/ caffine- they all are stimulants and can increase these attacks.
Try these along with reverse counting whenever you face such a situation to distract your self..you know that these episode always pass without doing any harm to you..so, try to be cool and in control of situation.
If these tips work -fine ..else, it will be very neglegent on your part in not visiting a psychiatrist.
Wish you good health and speedy recovery.
