My Dad Abandoned Me And My Brothers And Sister Followed Because I Could No Longer Accept My Stepmother And Stepsisters Abuse.

My dad had custody of 5 of us. I was oldest girl when mom left I was 11yrs old. I had to do (moms job) cleaning,cooking ect..everyday even though we were 1-2yrs apart i did all of it, they had no chores. Physically dad was there otherwise I was ignored I was lucky if he knew where I was but was a good kid despite being so alone at home. My baby brother had juvenile diabetes at 8 yrs old. He died because (I FOUND OUT LATER HE WASNT TAKING HIS INSULINE)AT 9yrs old. The night before he was rushed to hospital I screamed at my dad telling him something was wrong with him I was so worried. He blew me off (cause I was the stupid little girl)without even checking on him telling me its just a stomach ache. I couldn't believe he wouldn't even check on him he went right back to bed I remember being so mad. I stayed up with my brother rubbing his head telling him everything will be OK I was 14 yrs old. He died a week later after being in a coma. Brokenhearted I continue doing everything with no help or appreciation. I'm 19 yrs now and dad gets married and she has 2 girls 10 and 12 yrs old. They were great at first i was so happy to have a mom. than stepmom would start making insulting comments jokingly where I would think to myself what? Is it me or is she being really rude. I couldn't figure it out. They were totally different they were materialistic and the girls were spoiled brats. I've been through hell I am down to earth all I wanted was to be happy. Than my sister 19 disobeyed curfew so stepmom fought with her than gave her the silent treatment along with her daughters and tried to manipulate me into going against my sister and join them. My dad did nothing and my sister left sleeping in her car for months and staying wherever she could b4 settling down. Some time goes buy I am working full time and out with boyfriend all the time. Never disrespected them was always helpful and polite. One day as soon as I woke up and I'm attacked the 3 of them cursed me out your nobody who do you think you are ect..for about 20 min. I ask what did I do and stepmom says you know what you did. Mind you im being yelled at by my stepmother and her 2 tween girls.I was clueless. I tell my dad when he gets home and he pleads with me to please ignore them for him. Now I get the silent treatment along with mean looks whispering to each other just mean bully childish stuff to upset me. Than they get my future sister n laws to join them one I was friends with for years they are being fake nice to me now. Im not stupid ya know when someone is treating you different. My brother finds out the reason why they started with me was because I turned the tv on when my stepsister was sleeping or it was curfew they can't make up which one it was or is something else? Im amazed to how petty the reason. (I think she married to secure thier future and planed on getting rid of his kids) Anyway I saved money to leave cause it was a nightmare and my dad does nothing but kiss her ass. They know I'm leaving cause I'm storing kitchen stuff ill need for apartment. Than bitch leaves moves out when I leave and my dad is now alone. I feel horrible and want to stay with him but I made a promise to move in with my boyfriend who was living with his sister and her family after he lost his parents. My dad is mad at me for leaving him. He made me live in hell for almost 2 years constantly ignoring my pleas for help to open his mouth and stand up for whats right and im the one he's mad at. After my brother moves in with his family cause he can't afford a home. My dad still talks to stepmom. After 10yrs brother moves out step family moves back. I forget the past and start a new, I love my dad. I know he is week and lonely and want him to be happy. Everybody's happy we are all older with families. But thats not enough for stepmonster again she gives me the silent treatment after my neice complains to me about all 3 of them. She tells me they are mean to her use her to babysit and is actually scared of stepgrandmother. So my sister n law goes back and tells stepmonster I said I'm done with her and the bully bullshit starts all over again. Next I find out I'm not invited to my other brothers twins graduation party. When I call my brother to ask why (cause I have never missed 1 party for any of my niece and nephews) I was told my stepmother would feel uncomfortable so me and my kids couldn't go. I was very close to all of my neices and nephews. I chose not to visit my dad at his home cause she won't speak to me I'm not wanted at their home and she let's you know it. My dad feels I should of ignore all of it and still visit. I tell him he can visit me and his grandchildren any time. After a few visits and him trying to get me to go to him I tell him I'm tired and don't deserve any of it. I mean have I not done enough for him why do I have to deal with this constant bully child stepmother who treats me so bad. That was the last time I saw him. Accept for a few nieces my family doesn't speak to me cause they feel I should put up with whatever they do to me for my dad. I am heartbroken feel betrayed nobody cares how I feel, I just don't matter. Am I wrong. My lifelong friends were not surprised my dad never stuck up for me. Should I write him for closure b4 its too late he's getting old. Help
