Do you own a ouija board? If you can channel the spirit into the planchette - or I could help you with that - that’s usually a way to get decent communication. I used to find that when there was information I was somehow struggling to get through the usual methods that I would get things through sideways via ouija.
I have some secret weapons that I generally don’t speak about and do not under any circumstances teach. So don’t think I’m at a loss to help you. I just really think you should learn to do as much as possible for yourself, and trust yourself. You are really good at verbal channeling when you let yourself relax and stop trying to figure things out. You’ve got to stop worrying about confirmation and “doing it right,” and trust yourself.
