anyone here cut off thier parents?

because i am really thinking its the only way i can survive mentally.
mother-think joan crawford in mommy dearest
father - ignorant,critical and depressing
brother- still lives at home with parents at 25 and they give him everything and always have even though they never gave me anything.

i wasnt a bad kid. i got ok-good grades and stayed home instead of going out. i never back chatted or did anything wrong that would warrant they type of treatment i got. and it really p*sses me off that they give my brother whatever he wants and pay for his insurance and cars and even gave him a job at my dad's company.
he never does anything for them.


i on the other hand had to pay someone to teach me to drive,bought my own car, paid for my braces,clothing and when i lived there i even gave them money and cleaned the house etc.

i just dont understand. i am jealous and hurt and i feel like a got a raw deal. they still continue to say hurtful things to me. like i sold a photograph and my dad says "i wouldnt pay that for a photograph" and when i sold a painting my mom said "why would anyone buy that" i lose some weight and they tell me i could lose more (in the amount that would make me underweight)

i am just so sick of it. i have tried boundries and stuff like that. they deny the abuse ever happened. even though my little brother verifies it did. i think its messed up that someone would make thier kid feel like they are losing thier mind rather than admit to what they did was wrong (abuse)

i moved out when i was 18 and have tried to make it work with telling them how thier comments affect me and what not for 10 years now. and they are just not getting it. the older i get the more they seem so wrapped up in themselves that they cant see anything other than what they want to. it really wierd. and its depressing and draining. i just came back from a visit that was so draining i crashed and slept for 18 hours i was so exhausted from being around them.
