i am having writing problems. writing assignments/stories/essays etc.?

i fear that the ppl who will read it will think im being silly or stupid. like im not a good writer.

i am studying english literature. i know im good in the subject and can write admirable stuff. but every time i sit down to write, the first thing that comes to my mind is somebody else can write it better than me. and i know who that someone is. its my elder sister. she studied literature too. she made all the notes and got really good marks (highest in her class).

i know that i can do the same. i just cannot make myself make notes. i study from hers. but i really want to make my own notes.

i usually write my original on the test. when i HAVE to. and i know that the teacher doesn't care if im being silly or what. all she has to do is mark my work.

i also want to write some short story for myself but all i keep thinking is what the reader would think of it.

i hope u understand what im trying to say.

thanks.
