It's just nervousness. Your little mother may be someone you subconsciously don't want to touch. It's just that you magnified her words in life and linked them to some embarrassment in life. Nine times out of ten people are unhappy. Don't exaggerate their dissatisfaction in life. Keep yourself in a state of mental tension, which depends on your state of mind. Communicate with friends more, go out for a walk more, breathe fresh air, express your depression and adjust your mentality.
