Anyone feel like they have to relearn how to live life after becoming a mom?

My little one just turned 3 and he is the absolute love of my life. Having been so busy being a SAHM while hubby finished up med school, we are now moving to a whole new state for his residency. And i’m kind of worried. Not because of the change, really, but bc I feel like I lost who I used to be. I used to set goals for myself and be interested in learning, reading, hobbies, etc. For the last 3 years (i was laid off 6 months into motherhood too fyi) I have been doing nothing but mom-ing full time. Of course, i LOVE it. But I do think I’m missing something and it’s most likely that I’m just missing… myself. I nap when he naps, I wake up when he wakes up, I try to cook, clean, keep him screen free and entertained. I dont even know where to start with getting back to ME… Anyone relate?
