Weird

I'm just passing through this weird phase where in a lotta things are running around on my mind all the time. Yes! I mean ALL the time. There're things that make us feel good and happy; and there are things that make us sad and depressed, but weird? how can you feel weird about certain things? Is it a mixutre of good and bad feeling? What is it? If its something weird, how can we conclude it as its weird? No wait! How can use weird to explain 'weird' when the word itself is not explained? Isn't it a very confused word by itself? I don't know what is it or what do I have to do with this word.. But this just explains the phase of my mind..
