We have a suggestion. Perhaps it'd help you. We What'd happen if you just spoke out loud to them? Or in your mind? if you live alone you can do it aloud. If you're not alone in your house then think what you want to say. They're probably as terrified as you were. We can understand that. Also, leaving brief notes out that you're afraid and that you don't intend to hurt them might help. We've been multiple all our life but communications weren't always so wonderful so we understand you completely in that area. And maybe eventually you, them and your friend can work on something to take away the cold shivers. Good luck and we're all here if you need us.
