Confused Emotions

I'm a little confused emotionally today. First thing this morning my son asked me to help him buy something over the internet. Then a friend I haven't seen in over 20 years called me and said she was at a resteaunt down town and wanted me to meet her. Well, I told my son. He just got mad at me. This is my middle son. The one who lives with his father. Anyway I gave him my card and the info. he needed He was still angry when I left. I had to go see her. She was one of my closest friends. and has lived in Sacremento for years so I couldn't see her.
Now I am home. I have been trying to get things together to have a garage sale this week end. i still haven't sold the things from my grooming shop. My shop is filling my garage. There's no room for my car. I have asked my youngest son to help me. He has done nothing but complain, argue and whine. I can't ask him to help me anymore. He wastes my time and upsets me.'
My dad told my I am like a burr. He has already told me how much I am like my mother and that he wish's he hadn't married her.
So now what. What the world am I suppose to do. I am disabled with a back injury and severe tendonitis issues in my right arm and osteoarthritis. How much lifting, cleaning and moving can I do.
This house needs to be cleaned out My dad has been hoarding for 40 years. I can't sell it if it's packed full of junk. And most of it is literally junk.
I feel like I had a break down three years ago and without treatment or support I have not recovered and it's getting worse.
I don't know what to do. I can't do all of this on my own.
I just want to move back into my own house, even though "they" tell me this is my house, and just be. Be left alone. I was happy once, I think. I don't remember. But, I do know that's it't time. I am 53. My mother died at 48 my brother at 49. I don't want to waste anymore time with this bull. I wish my family would either help me or get out of my way. I love them but they don't know how to love me.
