HI
If someone who knows me sees this don't out me.
My mum died 10years ago leaving myself, 4older siblings and 1 younger sibling aged 4 years old. I was 15.
I stayed with one family member my younger sibling went to their dad (my step dad been there since I was 18months but had our problems during my teen years and his depression and drinking problems. Looking back he was very abusive towards my mum, my siblings and I.
At 18 I had a family fall out and most of my family cut me off as I was suffering with severe depression and wasn't very good to be around. I fell pregnant and placed the child for adoption as I couldn't look after the child.
I then moved to a new area to start my life again.
I fell pregnant with DD1. Social Services become involved with my past and as they had looked into my family it was decided some family members are very emotionally abusive (my Grandmother especially who I stayed with). As my younger sibling was only 8years old I made it clear I wanted to stay in touch with him. Myself and Social Services decided that a Facebook/Email would be best and if we met each other with his dad it was to be away from the house so the other family members never got to know where I lived.
That has happened. Since DD1 was born my step dad (SD) has met her twice and sent no birthday cards, xmas cards or anything. I kept him on my FB for my younger sibling. In the meantime I ended (with consent from SS) up with 2 of my older siblings on FB. 1 has met DD1 1 hasn't as SS classed him as a risk but OK to have indirect contact.
I started having health problems and was admitted to hospital close to my "family" but they wouldn't visit me as they were too busy. Everytime I was admitted and had scary surgery they were always too busy.
Over the years I have spoken every now and now with my "family". DD2 was born this year and not 1 of them acknowledged the birth or the difficult pregnancy I had due to my health problems.
I then realised my younger sibling had a new FB account. My younger sibling sent me a message saying "I am sorry but we never meet and I don't need you" 
it broke my heart as my life before my DD's were my younger sibling (YS) and now my YS never wanted to know me.
So all along I have only kept my family happy so I got to know my YS. Now that is not going to be happening. I don't hold against my YS who is now 15 and has their own life. How do I cut off from the rest.
I know it seems easy but it is so hard to de friend. They don't have my number and I keep thinking "maybe they will change and want me and my DD's" But I doubt it.
It feels like a big step and I know I need to do it but how can I? We all promised my mum when she was dying even though my SD was sleeping with a woman who he was having an affair with and wouldn't answer his phone when the hospital phones to say my Mum was dying so I had to hold her hand, me a frightened 15year old holding my mum's hand as she took her last breath, while HE was in bed with another women after telling me he was going to help, why didn't he help me for once, why did he leave me all alone to face my mums death that shouldn't have happened then 
sorry went off a bit.
I know we are never going to have the happy family that is pictured in my mind. I do have that happy friendly family with my DP's family. I need to cut my "family" off but it's so hard to do.
Sorry this is garbles but I've had a glass wine and looked at my "families" fb and all of this came back to me and I need to move on. I can't close my FB as I have a support network for my illness.
