If someone constantly makes you feel an indescribable discomfort, causing internal conflict, suppression, and loss of energy, then trust your feelings rather than your emotions. Many forms of exhaustion are not obvious; the other person may not directly hurt you, but they are always comparing, negating, or affecting your state. The most important thing between people is mutual nourishment, not mutual consumption. For someone who makes you uncomfortable over the long term, distancing yourself promptly is the best protection for yourself.
