<human>: So both my brother and myself had aspirations to move from the East Coast to Los Angeles. I am VERY lucky to have a sibling that I trust and is a good person and it makes the most sense financially that we live together for now at least to adjust to the cost of living.

Living in LA isn't as expensive as one might think EXCEPT FOR rent and real estate. Good lord, everything you hear about rent is true. This means we share a one bedroom and have a roommate in another room. Those are the breaks.

I don't want kids, ever. But I feel like I am literally taking care of a toddler. I constantly have to run behind him picking up his messes, doing his laundry and putting it away (if I don't put it away he will not and it will stay in the spot I leave it and eventually will end up back in the dirty pile).

He talks (and his natural voice is very baritone and loud) literally from the moment he wakes up to the moment he goes to bed, constantly on non sequiturs and sidebars. He will keep my Roomate and I up so late because he gets off work on the late side (10pm) and usually doesn't turn off lights until 1am or so (this is with me in the same room trying to sleep) on the phone with his gf and 50% of the time they argue.

Any suggestion of house rules results in an argument. He washes dishes but otherwise I have never seen him clean a thing and if I just leave it for him to clean it just won't get cleaned at all. He's been non-aggressively oppositional his whole life so he gets resentful and moody if I try to tell him what to do. 

I've called my mom and complained to her about this lol and I don't know how to handle it. I know things will improve once we have a 2 bedroom proper apartment that is "our own" but as of right now I am on anxiety meds all day because otherwise I want to literally punch him in the face most of the time. And I feel bad because I know other people have much worse sibling situations.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: grown woman temporarily living with mid 20s brother who is basically a good guy but lifestyle differences are causing major anxiety and resentment in myself.
