Urge to behave like an animal when overwhelmed/stressed

I couldn't find any other posts online about this, so I'm coming here in hopes for some insight or mutual experience. Let me know if the flair is wrong.

For a quick background: I'm officially diagnosed with ADHD, have yet to take any medication. Recently I've been hitting a psychological/emotional breaking point (for multiple reasons I won't get into here). Sometimes, when I'm in this state, I have the sudden and very strong desire to turn into/behave like an animal: Can't talk, only make animal sounds like hissing, growling, purring, etc., move on all fours or hunched over (like dinosaur?) if two legs needed to traverse an area/reach something, biting, scratching, drooling, and other animal like behaviors. When in this state, my mind is usually empty, only reacting to surroundings, unbothered by human thoughts and worries.

I have no idea if this is some sort of adhd thing or a symptom of something else, I just want info on what's happening with me since google has been unhelpful, any insight would be great!
