Hello, I'm not the oldest member here but maybe I can help you. What did you do that you think you disrespected Demons or Satan? You don't need to tell me the exact reason ofc it's your preference. But maybe I can share you the experience of my own.
I did dedication to Lord Satan 2 years ago and since then I didn't meditate this is just my stupidity until recently, today I started my 40 days program and i feel much better, do I feel like any of Demons hate me , no. But I do feel guilty for not respecting them and I'm trying my best to apologize myself. Trust me Satan has a lot of patience and he understands and waits untill you're finally ready maybe you can try to have conversations with him one on one, no matter if you're spiritually open enough I would still talk to him about my problems and about my determination to seek for knowledge. As long as you treat them with respect they will respect you as well. If you're new try doing 40 days program or opening your astral hearing this will improve your communication with Satan and Demons. You should also read more about them and if there is a Demon you really love and respect try to read more about him/her, his/her past, names etc. I hope this helps you somehow.
