Why is life so complicated?

Today I was reminded of the reason why I left home as soon as i could. It felt like two seconds between me graduating high school and starting Uni. The Uni thing I now regret because I feel like I was way to young at 18 to know what I wanted to do for the rest of my life. But it did get me away from my hometown. I love my family more than anything but I do have a hard time living in the same house as some of them. I don't know why but we don't really mix well together when we've spent to much time in the same house.

I see myself as a strong person and it's really hard to tear me down. I easily brush most things of without giving any thought to it. But if it's one thing that can put a dent in my strong exterior it's my family. They usually don't mean anything by what they're saying and the things aren't said to hurt me but the way they are said just rub me the wrong way and makes me irritated and when I'm irritated and tired at the same time a crack.

I was almost certain I wouldn't go back to Uni after the summer and instead stay at my parents house for a while, just until I found what I really wanted to do. But I've been here for approximately a month now and it makes me wonder if I would be able to actually move back in here without loosing my sanity.
