Age regression

Does anyone else experience age regression? Today I found out I experience involuntary age regression. How i came to this conclusion, well, a couple days ago I had gotten into an argument with my partner he started to yell and I shut down completely. I felt like a child again, I kept asking for my Apa. Who was always their to help me with my schizophrenia symptoms and depression. I was crying uncontrollably, rocking back and forth and I genuinely felt like a child. Not like my behavior was childless but that I myself was my child self. It's hard to explain, but reading more on this topic was not only difficult but eye opening. Apparently age regression is correlated with Schizophrenia and PTSD. Which I unfortunately have both. Please tell me I'm not alone in this... I feel so embarrassed and ashamed. One instance I can remember is when I was 12 I would carry around a stuffy of a koala. I loved him and he literally went everywhere with me. Even embarrassingly would shower with me. He was in my backpack at school, I even have pictures of myself with said koala. I feel like this post is long enough and it's hard to explain everything but I hope someone else understands.
