I have no will of my own

shininggirlI have no will of my own

This is a legitimate expression in English, but it means that you have no ability to stand up for yourself. You are weak. You have no spine. You always go along with what other people want you to do.

On the other hand, it seems you are looking for an expression that means that others do not allow you to decide th

Now, imagine someone asks me to do something, and I feell I can't reject her, and I obey her.
Can I use the mentioned expression here?

For example,
She asked me to just sit down and do not talk. I had no will of my own and I obeyed her.

shininggirlShe asked me to just sit down and do not talk. I had no will of my own and I obeyed her.

As shown.

You can say it, but I have to say that I don't hear anybody say "had no will of my own" where I live. It's not an expression that's used much here. I might hear it said like this:

She told me to sit down and be quiet, s

That's great thanks.

courage also fits there grammatically, but it gives a different shade of meani

How about this one?

A shadow casted on me and avoided the moonlit.

shininggirlcasted

There's no such verb form. And anyway, things like columns, people, trees, and buildings cast shadows. Shadows don't cast anything.

I don't know how a shadow can "avoid the moonlight". (moonlight, not moonlit.)
Is the shadow supposed to be running away from the moonlight?

In short, you need to rev

Oh sorry! I wrote it wrongly in this thread. I wanted to write it here:

So maybe I can say:
A shadow was casted on her; someone had avoided the moonlight.

shininggirlA shadow was casted on her; someone had avoided the moonlight.

Let me repeat. There's no such verb form as "casted". Consult your tables of irregular verbs.

Also, I don't know how someone can "avoid the moonlight". I think you may mean that someone blocked out the light from the moon?
