@The-red-centaur I am sorry that the police dragged you in and surprised that the helpline called them :o!!! (I didn't know that they could/would do that kind of thing. I won't be calling any helplines in the future that is for sure). As for police I am very wary of them (I just don't trust them) you did well getting emergency to let you go home after all of that.
I am sorry that you are experiencing so many stressful thoughts at the moment plus not being able to sleep makes it 10 times worse. Is there anything that you can do to help you calm down like a hot shower, listening to music or going for a walk a bit later when the sun is about to come up?
