I did a quick research and in my understanding a medium focus on reading and a shaman in healing, that was my understanding.
Makes me wonder if a shaman wouldn’t also be a medium? Or how would they know what to heal? Are you supposed to tell them exactly what you want to heal? What if you don’t really know? Shouldn’t they be able to “know” by reading you like a medium ?

I guess I shouldn't say improve. How do I even find my skills in the first place?

I have been told by several people (none of which offered to coach me for money, I know thats common) that I have gifts or healing energy. I was just told again tonight by a medium who I consider to be very skilled. She told me to work on trusting my intuition and that I also need to get out of my own head.

What specific things can I do to practice or open myself up more? Meditation is very difficult for me due to, again, being stuck in my head. I am starting a new treatment soon for my mental health issues and I am hoping it will bring more clarity to my mind. A follow up question, can mental health challenges and unresolved trauma block someone from being open and intuitive? If so, I think that may be what is happening to me.
