They said it's normal..does it feel normal when every impulse you feel in your veins are uncontrollable each day? Does it feel normal in each uncontrollable action that you've dissociate to? Does it feel normal to impulsively sent texts/ impulsively share your secrets (possibly to the wrong person) / impulsively pressing on the 150km/h gas crying it all out wishing to bring yourself somewhere to end it all? Does it feel normal to feel empty on some days which could drag for weeks even months? Does it feel normal when there are times you just didn't wanted to share anything at all, cutting ppl out instantly and regret everything later? Which is the feelings of regret in potential healthy relationships or could be the opposite of healthy. Does it feel normal having to struggle between what's healthy and what's toxic? Yes the person you mentioned normal, do look normal. Have you ever thought that every inch of them is every inch of trying to control the impulse of doing everything and nothing at all?  It's the smallest thing that drives them nuts. It's the 'no intention to bring up the drama' that drives them nuts. It's what everything drive them nuts. They are normal,they are something, they are normal. 
(Even posting this seems like a struggle.. the urge to share is very real yet impossible..)
