I genuinely don't know what to do

My parents have been fighting frequently which usually leads to mom getting angry and refusing to sleep beside my father to instead sleep with me in my room. This has happened multiple times where she either brings in a mattress or sleeps with me in the same bed when she does the latter, it dosent end well because I start to feel her breathe into my neck/face whilst snoring insanely loud into my ear and I usually end up having to slip away silently to go sleep somewhere else (living room couch etc sometimes even on the ground when it gets too hot in there cuz no ac) and she would usually wake up to me not there and comes to find me, feeling bad and sleeping in the living room telling me to just go sleep in my bed and obviously because that's my mom, and I love her I feel super guilty and usually fall asleep thinking about it nonstop regretting my actions. The same rl happens when she sleeps on a mattress because her snoring is like of a 10 foot boulder beast that hasent had a wink of sleep in 100 years and suddenly decided that shaking up the whole atmosphere with his 2000 octave snores is a good idea. So God help me how the fuck can I sleep without waking up feeling like someone's been ramming an axe through my head nonstop for hours on end. (I don't even want to mention the amount of times I get from my bed to go eat or something and I come back to find her sleeping on my bed) any way I can just break it down to her very nicely?
