Meditating isn't working for me. Can't clear my head...

Want to increase my intuitive abilities but also don't want to be overwhelmed.

Sounds like some energy management tools and techniques that go beyond grounding would be helpful. Lisa Campion's book Energy Management for Empaths is really good as well as Wendy De Rosa's books.

There are other ways to hone and sharpen your intuitive abilities besides meditation. I've found doing inner healing work (receiving it from another or doing it on our own) clarifies our psychic abilities.

Getting to know your own energy and how it works can take time but usually working with a mentor will accelerate and support the process more.

I tend to have a lot of mental energy and I've found that doing a brain dump in a journal helps a ton. For some reason I need to get it out of my head and on paper otherwise my mind continues it's hamster wheel game. Also when I do mundane tasks (like washing dishes, cleaning, doing my hair, etc - things that don't require much thought but keeps my brain distracted enough) I'll get intuitive hits or messages from my guides. 😊🙏
