Hi why why do i get this coming back a back about harming people, could last for at least 2wks of thinking gonna loose control which i never do, but always feels like i was nearly close that time.....But then it will go but still get thoughts but not the worry with it, then could go a few months without it then ...here we go again, this mane worry has lasted about 9yrs just wont go away. In its anxiety because i,ve had for 26yrs-i,m 36. i fear the worry and dred etc. but why does it come and go...when it goes i no its stupid, but when in worry i feel like i was nearly close to loosing it or hitting some1....thanks please feedback....brian
