Feeling a lil Depressed ,help me before i do something a regret?

my mother says im selfish and mean sometimes. yeah sumtimes she treats my one of my eldest brothers better than me. high school she didnt like taking me to school because it was far and was about a 25 minute drive. now im in college and have a job, she has every reason in the world not to bring. and always say i have no gas and school is 6minutes driving distance. she puts so much financial burden. just when im at the brink of saving or almost financially secure,here she go i need 200 dollars. and my brother who make 700-900 dollars she ease the financial burden. in not making that great amount. i try to forgive and just make plans to get another place. am i wrong? Now My hair is relaxed and got done proffessionally for the first time by a friend, all a sudden she offered to take me to the salon and all a sudden she's claiming me when she found out i became a manager. this is the same job offered she told me to turn down. how do i overcome this and am i wrong for feeling the way i do?
