Why doesn"t my dad understand me?

I just turned 19 and I have an older brother(22) that did not graduate highschool, went to jail and got alot of tattoos, came home and smoked weed, then went back to jail till 2017. My older sister(21) lives in a fantasy world and did not graduate highschool.She smokes weed and has tattoos also and does not want to listen to my parents because she says she is grown. Myself on the other hand have graduated highschool in 2010. I was an excellent football player but i quit because i didnt want to play for that high school i was moved to by my parents, i could have boxed and went pro but i got side tracked in the streets. i went to a community college just for the financial aid money mainly because i didnt want to study there because it was high school all over again...My dad always said none of his 3 kids are different as i went through high school after both my bro and sis dropped out....I tried to prove to him that i am different by getting my high school diploma despite of the mistakes i have made. i did go and get some tattoos and he got mad at that and said im no different from my bro and sis...he moved me to alabama and i got a job as a cartpusher at walmart. i contributed my money in this household for six months. i then quit because that was not what i wanted to do with my time and i felt that i was being mistreated at work. but all he did was walk away from me with no words..that hurt me. pretty soon in july i will be going to job corps where i will study auto tech. and my dad still tells people that none of his kids are different when i am the only one making an effort to do something with myself. my bro is in jail and my sis is house hopping.becuz she think she grown.. and im here about to go to job corps and make something of myself but i am still always to him just like my bro and sis... he wont speak to me about it he just ignores me and it hurts my feelings. someone please respond.thx
