Hey, I have a very serious question. More like a survey. But anyway, I am open to hearing people come forth to discuss the demons they may be battling inside. And I am curious if you need help because I am too and need help as well. Just to better each others lives. I am a psychic as well and am good with emotional support. I am here with you and need help just as much as you do. This journey does not have to be taken alone.
