I have issues with my family

Well I have a lot of family issues and can't really talk to anyone about it so my brother is a huge douchebag and is a jerk to me all the time but I am a very forgiving person and can't ever hold a grudge on him even if I try really hard. He will be an ass hole to me for a long time and I just hold a firey burning hate inside but then always just say oh whatever and be nice to him again and I hate it because I shouldn't be. For example tonight we were going to Han out and watch a movie and I thought wow this might actually be good and then I walk down stairs to ask him about what we want to do and I stretch and put my foot on top of our wood stove (not on, hot, or dirty) and he flips on me about how I am ruining the socks and while I'm stretching back punches me in the gut and it makes me feel like I'm gonna through up and he said " this for being an idiot" and I didn't say anything and just sat down on the couch right behind me and started to tear up and he said if u are crying you are the biggest pussy ever and I just sat there for another 25 seconds and got up and started to walk upstairs and as I'm walking away he says you fucking pussy and I flipped him off and kept walking... It's just stuff like this that gets me sad.
And on my dads side (I have devorced parents) my dad loves him to pieces but doesn't really give a shot about me and it's just all the little things. I will give another example so me and my brother are hard core wrestlers and he is a scumbag and always needs to have what he wants so he is an asshole till he gets whatever it is he wants (but I'm not mean like that and can't be that mean so I don't do that) but anyway we go to the grocery store and my dad gets my brother whatever he wants like expensive athletic drinks protein bars expensive fruits whatever he wants and the weekend before I asked for one of those protein shakes when my brother was getting 4 for just one weekend he wouldn't let me get one. And back to the original story my dad is buying my brother all this stuff doesn't say thank you nothing. Most parents would ask the other sibling anything he wants right? But no he doesn't say a word to me besides asking me to get him a cart and bring it back after. Meanwhile he calls my sister who isn't even there and asks her what she was and gets it for her without any fuss and we leave with everything everyone else wants but except me. Another example this Christmas I got a simple g shock nice present right he got a 400$ smartphone like bruh and then last birthday my dad got me nothing and the birthday before that I got a couple things from goodwill and my brother got a dirtbike... Like my dad can't get enough of my brother but is sick of me I don't know what but he does On the Tehran hand my mom is great but still it really sucks and gets me depressed. If you read this thank you but please give me some advice
