I need to move out...

Okay so I currently live with my parents and have now for the last 2 almost 3 years and it's starting to take its toll on me and my parents. They don't understand that I'm sick of being questioned and having to explain every move I make and unfortunately because of that I now have an attitude every time I have to answer any of there questions. Well that just blew up in my face because now both my parents are mad at me because of my attitude problem. I feel like a teenager. I hate this, I hate conflict and of course, they take no responsibility and can do no wrong. When I tell them why I have an attitude and that I’m sick of always being questions for every little move I make they say my attitude is unwarranted. I really need to move out and get my own place finally. I was going to wait until April 1st, because I’m planning a trip to Germany in March and my mom is going to go through her radiation in February and March, but I think I’m going to start looking now for maybe February 1st. The only thing is though I think I will have to stop Jenny, because I don’t think I will be able to afford my own place, my new car and Jenny. I don’t know, we will see.
