Alone

Sometimes I feel like i'm alone even though
I'm walking with plenty of people
Sometimes every step i've take have fear and confusion.
I'm alone if I feel down I think there's nobody help

          me to stand and moving on?

I can say that i'm not alone cuz im with myself???

          sounds confusing right but it is absolutely true 
         you cant be happy if you not wanted to be it ? 
         it's just you nobody else???
