I can't stop talking to myself and arguing with myself aloud

I know this isn't necessarily an ADHD symptom but I was wondering if anyone else has this issue and if it's related to ADHD... I'm in my late 30s and have no schizoid diagnoses and have had no hallucinations except for PTSD flashbacks. I have possible hearing loss which has resulted in sometimes hearing mumbling voices. Anyway, I speak to myself aloud and often it is part of what I'm saying to myself in my head or a response to it. For example, saying "no no no" to drown out negative self talk or "meow" to interrupt negative thoughts. Sometimes when I'm having suicidal thoughts (it's just part of depression) I say them aloud when they're intense (e.g., "I want to jump off a bridge.") It's so weird and it only happens at home but feels uncontrollable at times and I almost slip up elsewhere. I'm going to explain this to my therapist next week and as a social worker I do have some insight into what is going on anyway but I wanted to ask if any of you experience this or understand its connection to ADHD if one exists. Thanks!
