The Impending Return

So... in about 5 days I will be moving back to university accommodation for my 3rd and final year of my degree. I lived in halls in my first year so you would think that in the run up to returning I would not be nervous about my return yet I am.
In fact I am more nervous about my return to halls than I was when I originally left home for halls in first year and I'm a little confused as to why that is. Maybe its because on my original run up to halls I was also excited to be going whereas this time there is no excitement and just the nervousness.
But as well as that I had an amazing group of people as my flatmates in my first year and due to that the bar has been set high and I'm worried that my new flatmates will not live up to the legacy my previous flatmates set which of course sets me up for disappointment. I am trying not to expect anything but it is very hard not to look back on my experience in first year. I guess I'll find out within the next month how it'll work out.
 
To make it that little bit more complicated halls is not where I want to be I'm not complaining because its a place to stay and not a bad place, beggars can't be choosers as the saying goes. But what I really want is a flat or a house that I can call my own (at least partially) somewhere where I can settle down and start my life yet at the same time I don't want any of that at all, sometimes I feel as if I'm growing up and leaving the rest of me a couple of years behind playing catch-up and it still wants to play with toy cars and barbie yet the part of me that is ahead wants a house and kids (which is an idea that it'll have to talk me into a lot). And I guess I'm talking about all of this because moving back into halls, signals the start of my third year, my last year, and that fact scares me shitless because I don't feel ready and I kinda thought that by now I should be, hell I was meant to pick up an idea of what I was going to do with my life and everyone else has plans, ideas and ambitions most people had these ideas before coming to uni, I came in the hope I'd pick them up... so I guess I'm destined to be a bum... cause I can't see my life panning out any other way, and I honestly never have.
