Big family, little me=problem

I have a huge family and with a lot of family comes a lot of talking and it causes all of us to be loud. The problem with me is that i'm the kind of girl who doesn't like to be around a lot of people, a lot of noise;I just like to be outside a lot and I like to be around nature. I like to think about my thoughts and just let it all go, but I have a problem with that. I live in a little town so there's not a lot of time that I get to go outside and the more thoughts I have the more I get stressed. Anyways about the family thing, big family+ quiet me=a huge problem. Last night four of my cousins came over to my house and I didn't like it because I had a lot on my mind and my step brother and step sister was already going to be there so that meant 8 kids including me was going to be at the house. When I got home my ma took me in her room and she started talking to me about all this stuff and how i'm just like her in this emotional way. I just wish that she would of listened to me instead of just talkin to me. So I started crying and we talked more, my ma knows that I dont like people in my room, going through my stuff, and doing anything that deals with me. I couldn't do anything about it so I just went in my room, and when i'm in a bad mood I like to clean, so that's just what I did. As you can see I have problems when i'm around a lot of people and when I like to have some peace and quiet and to be alone, but that's something I can't do in my own way,or control.
