I am starting to resent my brother?

My brother is 43yrs and he still lives at home with mum, but thats not why I resent him, he has never left home he has a good job since he was 21yrs and for the past 10yrs he has not paid any living costs to my mum (who is 81yrs dad died in January so mum just gets a pension) he pays no bored, fuel, council tax she even has to buy his food and has to do his washing, pack-up for work, I left home at 20yrs and although I have had hard times I never looked back, he does very little to help around the home, he will cut the lawn and hedge but thats about it, my family think the sun shines out of his backside because I have being to prison for a breakdown 10yrs ago (only for 8 weeks, made fake phone calls to companys, taxis etc, cry for help), but I have come back from that I even started my own company and have sorted myself out but my family still look at me as a bad person, I am starting to resent it all.
