Why is this bothering me so much?

Today I turned 20 and had a great day and night with my friends and family. My mom was very kind, yet when I get home from hanging with my boyfriend, she’s drunk. Intrusions come about blaming myself, I know it’s not fault, but I feel the urge to fix very broke people. I did it with many friends and my mom, but those are just compulsions. Besides that though, my birthday was one of the best and I’m so grateful to live in an amazing state

I went almost 24 hours without sleep yesterday and worked a 10 hour shift so when I got home I went to sleep because I was so exhausted and also sad because my mind was driving me crazy I couldn’t even concentrate so I went to sleep and I remember being half asleep last night when my mom came home she was literally screaming at me and I remember screaming back saying that I wasn’t going to talk to her if she was going to speak to me that way and she was being so mean to me last night and I really don’t even want anything to do with her. I’m 23 and can’t afford to move out. I even cleaned the house yesterday for her like she asked me to and she came home literally screaming and yelling at me for no good reason all because I was asleep at 7 or 8 at night because I had gotten no sleep since 7 or 8 the night before. Why would she just scream at me? I don’t understand why she treats me the way she does. Maybe I deserve it? I don’t know

I pointed out to my mom how she can help by not giving reassurance. She was resistant to this idea and said," I am trying to straighten out and live MY life and I cannot get involved in that pathology you have going there and doctors don't know what the heck they are doing" I understand why she feels this way, but i completely disagree and also find it mildly annoying. What really irked me though was that she then started giving me advice about how to feel better by "embracing my inner child". She said she's had a ton of trauma in her life so she is qualified to speak on this. What does your inner child want? What made you happy from your childhood? At that moment i just wanted her to stop proselytizing about what works for her, but doesn't necessarily work for me right now. So i said I love you mom, but i need to walk away from this conversation right now and go to bed because it's upsetting me. I am an independent adult so my mom is not legally obligated to do anything to help me. I also don't live with her so this is not (fortunately) a daily experience. Don't get me wrong, my mom is amazing in so many ways (and i DO believe that leaning into ones inner child can be liberating), but i find this really saddening that we are so much on different pages when it comes to medicine and doctors.
