I Feel Neglected, I Can't Take It Anymore.

I want to run away, my story may not be as bad as others but mental abuse is just as bad as physical. me and my mother have almost always had a pretty good relationship, different then most teens and there mom's but when my mom started dating her boyfriend mark, things changed. She used to be layed back and now she is uptight, and acts completely like mark when she used to be a mom that goes hunting and gets dirty & muddy and isn't afraid to have fun. But now she is uptight, and yelled at us for 30 minutes for not changing the toilet paper roll, because we had put new toilet paper on the toilet but didn't put it on the dispenser. i NEVER get to do anything with my family, my mom cares more about her boyfriend then she does me and my siblings. Example/Proof: I have NEVER been to the dentist my ENTIRE life, one day my mom had finally found a dentist that was open past her work hours and she was going to schedule but decided not to because it would interfere with the time she got to spend with her boyfriend. another time: when my mom and mark first started dating she would always ask me if it was OK for her to go out or if i would rather her stay, i pretty much always said it was fine until 1 night when i really badly needed her help with a school project, but then when i told her to please stay because i needed her help she yelled at me and called me a spoiled, selfish brat who didn't care about anyone but herself. ANOTHER example: Just today me and my mother were having a sentimental moment where i was showing her some stuff i made with clay and she was complimenting it and saying how pretty i grew up to be and then mark got there and i asked if i could show her some more and she said no because she had spent enough time with me and now wanted her "boyfriend time". Also, Mark isn't really that bad of a guy, he is pretty sweet and he treats my mom awesome but she is different around him and she doesn't see that because she loves him, but her whole personality has changed since they started dating. And YES i HAVE confronted her about these things and told her how i feel, me AND my 18 year old sister BOTH told her how we feel and she was um-mature about it, she yelled and screamed at us and called us the worst kids ever and she decided not to feed us because she said we "didn't deserve her services" and she didn't drive me for school for the whole week that she was giving us the "silent treatment" so i missed 2 days of school until i finally just rode my bike and hitched a ride with my friends. My mother could care less when i get sick or hurt, EXAMPLE: a few weeks ago, when we were packing all our stuff for the move, my mom found a key. None of us knew what it was to so i asked her if i could see it to see if it was mine, and she said "no, i don't think it is" and then i said "well i am missing a couple keys on my key chain so can i see if it's mine before you throw it away" and so after asking twice since she ignored me the first time she screamed at me and yelled "fine wanna see the ******* key, here!" and she threw it in my room and it hit my forehead leaving a pretty deep cut. I just sat there trying to get it to stop bleeding so my mom started yelling at me for not packing and i showed her what she did and all she said was "well that's to bad, you shouldn't have annoyed me" (btw: the key WAS mine) EXAMPLE 2: One morning i felt really queasy and sick and i could barely even stand up, i was LITERALLY falling down when i stood up, my legs were jelly. I told my mom and this was her reply " I could care less how sick you think you are, your going to school anyways, so get dressed" and then later when she forced me to go to school, i totally collapsed during the 5 min. break between 1st and 2nd not blacked out but fell down and had to crawl to the nurses office because if i stood up i knew i would puke. So my mom started yelling at me in front of the nurse about how i was faking and she wasn't going to take me home so then to prove to her i wasn't faking i puked, and my mom just shook her head and took me home not even caring to apologize to the nurse or me. there MANY other examples of this one but i can't list all of them. My mother try's to keep me from seeing my fater which right now is the only person keeping me from running away, along with my sister Marla. If it wasn't for them and some of my friends, i would be long gone by now. and my mother neglects me and my siblings, which is pretty obvious if you couldn't tell from the above examples. Some days I feel like dying and just packing all my stuff and running but again i wouldn't want to leave my father and the rest of my family, i just want to get away from my mother. And at times i do love her but there have been more times i have cried myself to sleep because of her yelling and screaming and calling me worthless, then there have been me going to sleep with good thoughts about her. I have caught her talking about how she wished we were never born and how she wants to give up cuz were selfish kids just because we didn't help clean up the dinner table, which btw: i DID offer but she said "oh, no, you wont be much of a help anyways" So that's the reason i feel like running away :/ comments?
