You Changed So Suddenly

For about a year now, I've been working on a project - in Finnish, unfortunately, so I have absolutely no one to show it to - that's become one of my longest. However, it is the one that I already mentioned, which I had all figured out and then completely run out of inspiration, since it was not inspiration-driven project anymore. I started feeling like the whole idea was stupid, I didn't like the way I had written it, all the details of this and that seemed out of place and useless, the plot and other things in it seemed imagined, not to pertain to the real world at all. Even the names were ridiculous to me.
I had completely abandoned the project, until last night. I was going through some old poems and stories, looking for things I had written for or about my boyfriend (since he never remembers that I do have written these things), and came across this story. It is, more or less roughly translated, called 'You Changed so Suddenly'.
My intension was only to give it a quick look and then move on to see other stories I kept in the folder, when I surprised myself by getting stuck at it, only noticing that I was still reading after about four pages. And then I read it till the end, only skipping a line or two here and there. And my conclusion, now, after not writing on it since last summer, I think, is that it does need some minor changes, but everything else seems okay. Yes, it has been written in a way that is very rough and straightforward, but that can be fixed when it's finished.
So, now I'm equipped with loads and loads of inspiration for this story, but I'm afraid to 'pick up the pen', since I have Sparks to write, as well, and my problem with this story is that when I do start writing, it gets so hard to stop that I write until and far beyond a suitable time to go to bed. And all chores and everything else gets left undone.

Oh, I almost entirely forgot to actually tell what the story is about. I don't want to give out too much, since might be that I will still change some things, and I wouldn't want to 'spoil' it for any future reader. Anyways, the main idea is that there is a girl, from a big family, whose closest sibling is her older brother. The problem arises when the girl decides to become a police officer, and her whole family (almost) seems to be against her in this. She then learns the reason for this, which is that the older brother enjoys a rather active criminal life, as did their parents before him. She doesn't want to give up her own dreams, however, especially since she has met someone special at work, which provides the story it's romantic content, even though the main idea is the one about the rivalry of the previously inseparable siblings. She still feels the connection to him, and therefore tries to protect him from her colleagues, even though he does everything in his power to sabotage her new career.

Today, I also made a 'Summer to do' -list for myself which includes different things around the house as well as regarding writing. The things about writing are Sparks, of course, 'You Changed so Suddenly' (continuing and possible translation), translating one other story, and doodling with poems. It's a very private literature summer camp designed for my purposes only! Let's see how much I actually manage to do. Oh, and I also decided to try my hardest in order to have at least one bigger project, whatever, or of whatever sort, it would be, by the end of my third year in University. That basically means by next year's summer.
I have faith. And fear.
