1-I am worried to be alone.
2-Being alone worries me.
3-I am worried about being alone.
In which case:
a-I am alone and that worries me
b-I am going to be alone and that worries me
c-I am worried that I might be alone
Thanks Fivejedjon,
My question was what were the meanings of 1, 2 and 3.
I wanted to see which corresponds to "a", which to "b" and which to "c".
