life is passing by and im not really here

I am going to be 30 this year and I feel like I am not here and haven’t been for a long time. I got diagnosed with ADHD when I was 23. It never affected my attention span in school or anything so it was never a concern. I got tested because I realized in large social gatherings I would zone out and binge eat and then come back who knows how long later and think “what have I done and where am I?” Since then I have gotten married, had a child, left a career for another to now being a SAHM. It’s like I remember those things and other things, but I don’t know how I got here. I know time moves very fast but is it normal to basically feel like you are just waking up? I genuinely feel like I am still 17 all of the time. Would meds or anything help? Or is it just life?
