Internal Echolalia

Just learned the word for what I always experience in my head, Internal Echolalia. It’s when I repeat a song, word, or phrase in my head over and over. Sometimes it’s because it makes me feel good, sometimes it’s because of rejection or shame, and sometimes I don’t even know why. I can never stop it. Sometimes it only lasts a few hours. Sometimes it lasts a few days. The earliest I remember doing this was when I would walk home from school in elementary school. I always thought it was something everyone did until I learned about my neurodivergence. Lol. ????
