Family,friends,disability and life

I grew up in a dysfunctional family as many others did. Father Molested me,mother I believed knew but didn't care till she found out it was happening to my older favored sister then she left my father. Older sis and brother are from another man. ( married man) We are now all in our 40's.
The divorce when I was 12 me and mom never got along I was with my father till 14 and then on my own.
I to this day have never had another Christmas or Thanksgiving with my family. My mother likes tearing people apart, me and my brother do not talk not sister, non of us are in contact with each other and my mother likes it that way. She is a person who thinks of herself, pats herself on the back very self centered and if it's not about her she doesn't take anything else seriously, like my health issues.

I have made many attempts to get along with her go visit her which she lived in the next state and now just 2 hours away but does not make a difference.
Too many times over the years she plays these phone games and picks the cell up and hangs it up never calls back. A situaltion happened last August that stressed me out to no end she almost died my sister was at the hospital along with the rest of her nasty family and it was like a gang up party on me. The come from backwoods Oklahoma and don't like the fact that I will out them on all the Molestations in her family and my mom is the same she will defend them. Your suppose to sweet it under the carpet and not talk about it.
My Dr finally told me do not answer the phone to my mom anymore he call to me was 5 months ago and I did not answer it.
I have no Idea how to contact my brother but would like to.
I made the biggest mistake of my life by leaving Houston and moving to Oklahoma. I have lost all my friends and not made new ones here. It is very lonely for me, no one has any idea.
I am Disabled with Neck and Lower back problems and need lower lumbar surgery and no one to help me. Already had neck surgery and need another down the road. I have knee problems and they are worse now due to quitting smoking I gained 50 pounds. And no I am in no way feeling sorry for myself just stating the facts. Also need Rotator cuff surgery.
All of this has begun to be too much to handle for me. When the friends I had only wanted to tell me about their problems but I could never talk about mine. That's when you hear them talking to other people in the room. They don't have time for mine.
My dr Also told me I needed new friends that are not selfish, somehow I attract these kind of people.
Now I don't know how to even find girlfriends with the condtion I'm in.
I've always been a positive person with my glass 1/2 full but it seems to been leaking out slowly.
Life is hard when you don't choose to be a loner and have no family.
I've not dated because I why would a man want to take on my disability problems?
Can anyone relate to how I feel or my life?
