TW self harm maybe: 
For example walking over a bridge and you’ll just get a little voice in your head like ‘jump off. Just do it. Now. Quickly’. Or anything like that?! I’m struggling at work today because we have this boiling water tap to make hot drinks with and I had the same voice there just telling me to stick my hand under the hot water. I never usually act on these thoughts but it makes me feel really overwhelmed and scared and panicked. 
Just to add, I’m not hearing voices, it’s my voice in my head
