Never be Carefree

I have not been able to relax completely even though things have come down a whole bunch of tension notch4es since my mother went into the hospital in December of last year.
I'm able to stay in my own apartment most of the time now, like before, but I can't relax. I no longer have my carefree life. Well, it was never carefree but it was my cares that worried me. Now I have my father, brother and sister also on my mind.
I shouldn't have to be worried about them. My father is cared for much better than he has been for years in the living assistance care he has now.I don't have much worry about him, actually but it is stil one more thing I have to take care of and have some responsibility for that I did not have before.
Though my sister is no longer living with anyone, she is taking care of herself and has others that come in to help her. There is some reason to worry a bit about her but even when she was living with my parents she wasn't really much safer. My mother could not get around well and was almost completely blind, My father had Alzheimers and was more a hindrance than any help anymore and my brother was only there for les than an hour a day most days and that was in the middle morning or around noon. So she was pretty much already taking care of herself already. It is just that she isn't used to being alone.
And though I wish I didn't I do worry about my brother, I had no idea he was so irrational and irresponsable and that my parents ahd been taking care of him so much all this time. I knew they were giving him money but I didn' t know they also paid all his bills. He has been living on his own but has never matured past being a teen ager with his parents taking care of all his problems for him for thirty years. I've cut him off form all but what he will have when they are both gone and he will have to learn to live with it. It isn't a bad thing, he is pretty much taken care of if he would live like a normal person and be frugal. It is very doable. I have been doing it for twenty years myself. But I worry that he is too irresponsible to do it. I don't know if he will be able to take care of himslef. Not that I am going to help him but I still worry about him.
So I find I cna't relax. Things keep coming up, someone calls, I see something on TV, whatever... and I get worrid about one of them. I never had these worries before. I took care of myself and let them take care of themselves. But now I have been pulled into their problems and thoughI can separate myself I cna't stop being worried.
The stress of the inkown is almost gone and I am settling into what my life has become, The anxiety of my finances is pretty much gone since I am now taken care of like my brother from the rent of my parents rental property but I still have to deal with al lof their problems. I'm the one that gets called when any of them have something happen. I never wnated this and do not wnat it now but none of them are able to deal with things. Though my brother talks big he has failed everytime soemthing has been given him to do, even little things. It always falls to me.
I hate this. I only want to be responsable for myself.
