Hi myjourney11 -
I agree with Anna - you are empathic. Empaths are like sponges - they can absorb mental/emotional and/or physical imbalances/disruptions from those around them.
Going grocery shopping used to be a nightmare for me - or any where that a lot of people had traveled through.
Shielding often helps the empath from absorbing so much (white light bubble around yourself).
Also educating yourself on the topic. Read about empaths or HSP (highly sensitve people).
You are not alone - and empathy is on the rise.
