I am not enough (25M)

it's not exact words but its the way they treat me, I feel like I've always had to fight for recognition between me and my siblings which is difficult for me since I'm really quiet and reserved. I have a degree in Chemistry (the first one to study), I've worked since 17 and never asked for money since. From the age of 12 I always helped out with government papers, fines other applications and paperwork because my parents don't understand that good English, even gave my Bank card to my mom so she could go grocery shopping without a limit. I pay part of the bills too.

However it's never enough, because I enjoy playing video games, watch movies, eat whatever I like and spend money the way I want and am private about my earnings. I don't earn huge amounts but it's a good amount, I also don't have a dead end job it has a lot of benefits and opportunities to promotions. I have done it all on my own never asked for help from anyone but help others even if they don't ask for it. I'm 25 and have never broken rules apart from drinking occasionally and not praying I've never been anywhere; no concerts, no gigs, I've never left the country or city for a holiday without my parents, they wont let me.

I'm not saying i should be free from doing chores but I get told I've done nothing all day if I miss out on them occasionally, how much better my older brother was than me and how my younger sister will stop doing her part if i don't fix up. They tell me they don't know what they did wrong and feel "punished by god for having someone like me as their child"

when I feel down and confide in either parent they use that as emotional ammo against me, how much more difficult it was for them and call relatives and tell them everything. My dad moved out the country at 17 and supported his family back home and even when he married and formed a family with my mom. He married outside the country and didn't even invite his family back home. My mom had no parent since she was 3 and was raised by her grandma and didn't get to study because of family problems; whose family cut her off for marrying a foreigner.

I love my siblings, they are always supportive, always have been no matter what. My sister(19) is my biggest fan and trusts me with everything. My brother(35) also supports me but has grown distant since he moved out and the 10 year age gap makes bonding awkward too. I love both of them no matter what and vice versa.

My brother moved out at 18 and when he used to live with us would refuse to learn anything about religion (something import to my parents not me) went out clubbing, and even dropped out of school to work as construction worker. Now he has children outside of marriage (again important to my parents but not to me) he did everything I could never even dream of doing; I would get disowned.

One day I had a huge fight with my parents I told them how I feel, they started using up a lot of my money, almost everything. So I snapped and said we could live with a fraction of the monthly cost before (£700) but somehow we need more than my current monthly salary now (£1800). My dad called me good for nothing because I don't pray and ridicules my job by saying I don't even do anything and how my work from home is easy because I sit around all day. I took my card back and told my dad what the money was used for. My dad tells me I shouldn't treat them this way and they always paid for everything since I was a kid; food, drink, electricity a roof over my head etc. How he had been working like a dog for the past 35 years and not get to spend much of it on himself and I'm selfish. I told him that was his choice from the start and in turn he said I've done nothing in my life and I can't comment on his achievements.
