Certainty

I think this post will be a bit shorter than the last one but i don't really have a plan so i can't really say.
this kinda ties in with recent posts i have read, particularly about growing up. life no longer seems to be so simple, i know there is a long way to go but as we grow up life seems to get harder and harder, more to think about, more that you just can't answer.
I used to be so sure of myself, cocky, confident, and i think this is still the impression that i give people but the truth is i am not so sure. i don't know what i want from my life now, or in the future, i don't know what i feel about people or about myself. i am not sure what other people think of me and this is quite a big change.
do other people feel this?
i regularly sit there, just thinking, i lie in bed awake, just thinking, occasionally i make a decision but often i feel different in the morning and nothing seems to sort itself out.
i used to be able to make a decision and right or wrong i would stick with it, i would give the impression i knew what i was doing but now i haven't got a clue. maybe i never did and i am just realising it, but making decisions is so hard. because, believe it or not lots of decisions actually mean something now and i am just not ready to make them. everyone else gives an air of certainty, its kinda intimidating, i don't know if i do the same thing. the truth is i am not sure about lots of things now.
so this hopefully sort of explains the blog title, it represents my feelings at the moment, the feeling that i just don't know and everyone else seems to.
i am just not sure
