My mum has been gone for a long time.?

My older sister was badly behaved; so she took her to dubai with my little brother. I really wanted to go. So my mum left me with my dad and older siblings (20 and above). And I'm 14. Okay so they've been gone for a year. And my mum came back 4 months ago for a visit. I thought it was ment to be me and her bonding but I realised my mum was still spoiling them when there not even in the country ! She was too worried buying them tvs, laptops, consoles so on to even notice my existace ! It freaking hurt me so badly. And then before I know it she left. I need a mum with me, I'm going through these horrible and tough changes and I have no-one to go to. I can't go to my sister because she's never around, and I can't go to my brother or dad. Its not fair, and I know if I go with my mum. My education would be ruined, and I'm even forgetting her facial features. And at my house, its not good. My dad he looks after me but him and my sister hate eachother. And I hate being in the middle of it all. Me and my dad were like the best of friends before, until he's just become so irritated with me all the time. I don't understand what I'm doing? He's shouting at me all the time when I've done nothing wrong? He'll shout at me if I close the kitchen cupboard . And recently my greatgrand died and he couldn't even tell me. My aunt did. My mum didn't even call me and tell me. I feel like such an outcast. No one cares about me. I don't know what to do? I just want to crawl into a ball and cry.. No-one pays attention to me. No-one is bothered about me. I'm suppose to feel safe at home, but really and truely, I feel safer when I'm not there. Due to having an intruder raid the home while I was there. And a few minutes later ended up being in hospital for 2 nights. Since that I've been doing everything thing I can, just to stay away from there. Like school clubs and stuff like that. I just want to know how to stop myself feeling like this.. I feel so unwanted & not needed.
