Before actually knowing what therianthropy was, I never understood some of my childhood habits (which are still with me nowadays ), but after looking it up, I found it was really interesting and it explained all of those weird habits I had (have).
Back when I was little, ever since I can remember, I actually would walk on my toes (like a dog or a cat does), howl, snarl/growl if I got angry, and I had some kind of 'phantom' ears and a tail. Because of all that, my parents actually had a test done on me when I was five to see if I had psychosis or something (I didn't, and thinking back on it, I am insulted that they would even consider that as an explanation), but after doing research, I have figured out that I am a wolf/canine/cat therian (can't figure out which one exactly..), and am still attached to my therian form. I admittedly still walk on my toes, growl if I'm angry, snarl if I'm REALLY pissed off, yelp or wince when I get injured, bite people if they put their hands right up to my face, and even still have that 'phantom' tail and ears going on (whenever I walk around, it's like I can feel the tail swaying back and forth, and when I'm sitting down, I feel it twitch and sway in response to my emotions; I can actually somehow semi-prick my ears forwards, and somewhat feel them go back when I'm irritated or sad).
I never thought there was a name for it, and I (foolishly) thought that everyone had the same thing going on with them, but I am glad I finally know what it is~
