I am moving from my mother's house

  I am moving from my mother's house to my own. It's a house enough for me, not big, not too small. What I am feeling? Well, I decided to move because I was feeling really bad with living in my mums house. She brings her boyfriend everyday, my sister does the same. We are in four women, my younger sister is still a kid. But my other sister has a boyfriend who doesn't respect things, he acts as if he was in his house. I was getting really upset. I talked to my mom but she did nothing to solve it. I feel as I had no house anymore, I mean a place where I have privacy and don't have to be all the time worried if there are men in house or not. What hurts me more is that my mom did nothing, she didn't care about me. So I decided to go away.I need privacy and peace. And I am just taking the last things in her house and carrying to mine. I think I was brave leaving all confort my mom's house has. At the same time, now that things are really happening I feel insecure. I have so many plans and sometimes I think I will not have time to take care of the house and take care of this plans. Bad feelings about myself are coming back. I am even doubting of my feelings for my boyfriend. When we are together and I finally stop thinking I feel good whith him but then those thoughts come back. Right now I need strengh and faith. I feel my self-confidence is down. I felt it was so ok when I finally started working but now the dark part of myself is coming back, with all doubts and doubts. Thinking I did everything wrong, I didn't planned moving and now I am having some problems. I feel like I don't wanna talk to anyone. I feel I am not a good girlfriend, he is been complaining that I am always fighting with him. We have been together for almost an year. Is this normal? I want to change this behaviour, I want to change so many things in myself. I am open for some words. Actually I need words. Thanks.
