I'm growing more distance with my mom and despising her more, I need help, how can I cure this...?

Lately I’ve been really irritated with my mom. Since she’s a flight attendant she comes in and out of the state and house…But when ever she comes back she just yells at me now-a-days. I love my mom…But Jesus… Never knew it would ever come down to this…She’s hard headed, she thinks everything she says it right and will work, she oblivious to most things, won’t let go of this guy named Mike (lives in Philadelphia) and just a lot of stuff that she clearly can’t see. We all have issues I know that and I don’t blame her… But lately it’s been to hard for me to handle…And another thing to mention same issues goes with my sister, sort of just with out the personalities and issues I explained on my mom…They all can’t accept the fact that I have someone and they really don’t except the eldest (she has one, but her mind is F-ed up and she has major issues too….But…what can we do?) But they all take it out on me…They’re basically setting up obstacles for me to just see my girlfriend. And it’s funny since yesterday I left and left a note for my sister to read that I went to her house since she fell almost unconscious 2 days ago (5/17/11) and apparently they won’t allow me to see her then…Just I need some help on this….So can you all…Please help me on this major issue? This will affect me greatly in the future I know that, that’s why I want to cure it now and not let it sit. Please…
