Am I wrong to feel this way...?

Well , I was born into a moderate/poor family.....it varies from time to time but at the moment were very poor because my dad got himself into debt just a week before christmas. He bought all these tools for side jobs he wasn't even 100% sure he had , and they quit on him....So this year I'm having to go on very little for Christmas. My parents use to spend $200 on me every christmas , and now its been lowered to 100.....that doesn't get you much now a days...and most of my friends moms just give them 100 to go shopping , not for christmas...so I'm probably just going to get art supplies and some cloths.....my mom hardly even agreed to get me some new school shirts which I needed because mine are getting to small , and I need more winter cloths since I grew out of last years. I'm only 12 , so I can't really earn my own money...but I'm trying. You see every Jan. - Feb. my neighbor goes on a lot of trips and I watch her dogs. $10 per day. And then I breed my purebred rabbits , and the female is only pregnant for a month , and 2 months to raise the kits (Inexpensive to do so) , and each baby is worth $20.I already have a lot , I'm not complaining about the money situation really.....but my parents also fight day and night. Literally , and over the most stupid things. (My mom is a bit phyco) Like my dad accidentally scd my moms nose with his finger nail , and she freaked and kicked him out of the house.....she use to tell me and my brother when we were like 10 that our dad was going to go to hell , you don't tell little kids that. My dad is the best person I know. He lived on nothing , in a family of 12 , 5 brothers and 5 sisters. At one point they even lived under a bridge....His mom and dad died when he was 12 to...but he rose and went to college , got a builder's degree , moved to the U.S. when he married my mom (Dads Costa Ric an , Mom american.) and got a good tile job. And he's still the nicest and most giving person I know. He's just a really big push over and my mom is VERY controlling and jealous....she checks my dads phone everyday and won't even allow him to have his own facebook let along even talk to girls. On the other hand my mom is still friends with one of her ex's from when she was a teenager , and talks to him everyday. She's even cried over him because they were in a fight , she talks about him 24/7 and claims to hate him. I'll be on the computer and she'll randomly say "what do you think is wrong with ______ , I mean (blah , blah)" Its annoying , because its so obvious she still has feelings for him. My brother is very sweet to , but he got my moms temper...whenever he gets mad he hits me....and he's very strong. He's 16. I mean I have a lot , and I'm most thankful for my animals , because there the only things that give me unconditional love , and are gifts from my parents that will stay forever (I want to be a vet) , but I can't help but ask why god put me in a family like this....My mom is Bi-polar , Jealous , Controlling , my dad spends WAY to much than he should , my brother's abusive sometimes , and were poor.....I thank god sometimes though , for I know its shaped me into who I am , and made more thankful. But really , if he knew this family was going to cause me so much pain and suffering sometimes , why put me in it? Am I wrong to feel this way..?
