Confusion dilemma

Have I ever been more confused at any point in my life,I wouldn't know how to cope with all these confusions.It's the worst thing not knowing your destination,not knowing your future and not knowing where to launch and when to land!!!
Today I need to take a moment and think about what I really want to do with my life.Do I just wanna get my Master's which only requires a GRE test or do I wanna go to dental school.You see at this point is the matter of timing,have I known earlier I would have taken my decision by now and I wouldn't be dealing with so much stress.On the other hand,I have to make up mind if I wanna keep living with these girls which I doubt it.It's really hard to get along with them,even though I have the least amount of interaction during the day,there are times that I feel like I wanna chew their heads and hang them from the balkony.I don't really know,at least if my parents were here ,I would be more relieved not to be so worried about their accomodation or my siblings'education status.Why can't I just be normal and not always think about what's going to happen next?hah?why?I guess it pretty much has to do with how much I expect myself and my abilities to come up with the possible solutions if not the best.I have to brainstorm my mind and find new motivations...
