First and foremost do as much research as you can.
This is not a science, everyone reacts differently in ability, strength, and purpose. You may feel stronger around your "green witch" however you need to understand that what you think you feel and what you believe you feel are two different things, when you use your logical mind, you will never be accurate or truthful in your empathic abilities. If you think she makes you stronger, you might be tricking yourself into a self-manifested placebo. It does happen, and you need to be sure that what your feeling, is actually a feeling and not an idea or thought. I am highly intuitive, answers come to me out of thin air, if I question myself, I am wrong end of story. No people or person have ever helped me be more or less intuitive, and with somethings nothing comes. The signs that come to me and my abilities are only manifested when they need to be, whenever I have an instinctive or intuitive idea, or persuasion, they always lead me to something much greater, or solve a problem that otherwise would have been much worse. This is something I've been practicing since I discovered that I was an empath at the age of 28, I spent nearly thirty years thinking I had a mental disorder and that why my mind was always scrambled and why I suddenly thought I knew something that I had no reason to know, yet find that I in fact did know, and it was for a reason. Do not expect this to make your life more significant in the god complex mindset, you are liable to abuse and mistreat others without knowing it, you will feel others pain, and you will think your going crazy, as you get older your understanding will improve as well as your ability and strength. Just know to accept it as it comes, and never show off as a psychic, it won't work if you try to make it. Live with it and accept you have a guardian angel, a blessing, and a gift. Keep a humble mindset or it may turn into a curse, and always no matter how much you learn or think you know, always accept you know nothing, or you will be unable to continue growing.
