I'm so sorry you're experiencing this hun! I get exactly that- awful visions of harming myself that get worse and worse but I really struggle not to do it!

Please, please keep on at them! Have you described to them exactly how you're feeling/ what you're experiencing? They really should get you seen asap! Put it back onto them and say you're getting worse and worse and make them give you that appointment!!!

Good luck! And loads of hugs
