first?!

sometimes i'll do things to make ppl angry while i' not aware of it.. or even hated bt ppl for things i done which i don't know or not sure it's wrong =(
yesterday night while sms with her i really wanted to with her!!! but can i? don;t know if she'll accept me...
i'm scare... normally i would relly try to have a relationship even once also can...
but on sec thought... a lot come up into my mind! will i be happy? will she be happy? will we last long? i really hope so! will she like otherppl?? will her parent likes me? will i do things for her rather than myself first??? is she the one??? a lot a lot of question pop up in my head... i scre i can't even be with her for one day because i think i'll ruin it!
i don;t know wat i should do.... i'm USELESS
