Hurt my parents?run away and hide? cant let them have ds for 2 nights

[StressedKarina]

My brother was arrested for downloading indecent images or 12 to 13 yr old girls. he has tried to kill himself over it with remorse and called poilce on himself and he is mentally ill but no really diagnosed, has OCD stuff he does about germs and is odd and says things that are delusions, is early 20's and stays at my parents wher he eats sleeps and watches tv is not well enough to go and sign on and not on any benefits is totally unable to function without my parents. anyway, even though me and dh hate him for this as it has affected my elderlyish parents badly, and me .they have no one but us to talk to and my child is the only good thing they have in life at the moment and have kept it secret from other fmaily. we thought it was a delusion but the police had him in jail for 4 days last week and he is on bail so it is real. well my parents still bring him round the other night he paced about my kitchen and ate things I was nice ot him and dont want to hurt my parents, but next week for oct break they think ds is still coming ot stay overnight with them and sleep in the bed with my Mom for safety and reassurance for 2 days and nights as I need to be somewhere, but I have arranged to be off as I dont want him to go there and dh does not want him in the house or ds to be anywhere near him. even though we know it is not boys he was looking at and not of the age group of our son either, so there is no risk according to my parents but still I think I cant send ds to them but I cant hurt my parents either, they need me and love my ds, also Xmas will be an issue as HE will be there obviously, unless he gets jailed. Comments? anyone? are dh and I right to want to keep our ds away from him, or are we being abit over reacting and cruel to hurt my parents. i cant openly be off with my brother as he was my mom favourite and is mentally ill and 'fragile'and paents would be angry at me and i would make their life bad if I upset him and then my parents would not even have us to talk to this is not my normal nickname and am only using it for this, so wont have to delte thread new email accont and eveything just for this post

very similar picture you are painting , I am 8 years older than my brother. I hope your brother continues to be able to live his life.
I hope one day things will change for my brother and something can be salvaged and that he changes a little bit and gets help.
you messages have been a big help, to know that others have these feelings and that peole can come out of it a little bit and live their lives a little.
I understand my Mother, it is her baby her favourite child, and she is in her late sixties and does not really know what to do.So I will continue to try and help them and keep my ds safe. I know that when my parents are not around he will become my responsibility and that is hard but maybe by then he will be better and a little bit different. conflicted Ilove who he was but i hate what he became

thanks everyone who replied
