I feel lonely without my husband.

He'll be back next week.

I'm lonely. /I feel all alone.

I hate being alone.

I don't mind being alone.

I miss you. *含有I want to see you和I want to be with you这两种心情。

I miss you, too. I'll be home soon.

I feel lonely without you.

I feel helpless without you.

My son died, now I feel empty. 我很空虚

I'm sorry to hear that.

I feel incomplete. 我很空虚

My life is empty.

My life is meaningless.

I'm all alone in this world.

I don't feel satisfied with my life.

Alone at last.

I'm finally alone.
