Hi, @marta! I’m Amethyst from Southern West Virginia. Welcome to the forum! 
It sounds as if you are empathic at the very least, if not full-on psychic. That’s a heavy burden. Here is a great Shielding Spray that might help you.
Sadly I’m not that psychic so all I can advise you to do is meditate, meditate, meditate. Grounding and Centering will probably help calm that. You can find the Meditation lessons Here.
Hopefully, some of the other members of the coven will have good ideas for you.
Wishing you love and light!
