Space Invaded

So today I was at work, and I got a call from my mom.  She asked me if I had seen her file of some sort, and I said no.  I get a second call while I am still at work, by the way I work at a pizza place so not really the best time to be calling me, and she started yelling at me asking me if it was in my room. I said no. She asked if I was sure because my room is a mess.  Yes, my room is a mess, but I have never touched said file because I have no need to. So I come home from work at 1am, go in the basement and find the file right away.  Then I go to my room to find that all of my shit that was on my floor is now moved everywhere and half of it is on my bed.  This pissed me off to no end.  I had my stuff semi organized into donations, need to put away, and need to pack for college. All of these piles are now mixed together, plus I have to move it all so I can go to sleep.  I feel like my space has been invaded and I feel violated.  The one space that was my own, the one space where I felt like I could do anything I wanted without fear of judgement or ridicule, has now been compromised. I am sooooooooo tempted to just go to my dad's house for the night, but like I said I got home at 1 am after a long and busy day at work, I feel sick and lightheaded, and I have to get up at 6:30 to bring my car in to the shop to get it fixed.  I am so tempted to either go into her room now and move shit all around, not caring that she's asleep, or writing her a note to fuck off and stay out of my room.  I'm not going to do either, but I am just so upset, and have lost all trust for my own mother.  She knows I hate people being in my room, and especially when they move stuff and look through things.  I don't really have any thing to hide, but it's just the principle of the matter.  I just wish she would have waited until I got home, and asked me to look for the file myself.
