I don't want

I don't want you.
Don't talk to me.
Don't look at me.
Go away.
I don't want xxx to smile at me.
I don't want xxx to look at me.
xxx is looking at me. Tell xxx to go away.

I've tried explaining, rationalising, reassuring... down to scolding and threatening. I'm still stuck and I don't know what else to do.

Please let this phase pass soon. I'm getting really tired.
