Emptiness

I dont know
I feel like being alone
In the middle of crowded
I feel empty
I feel so nothing
And hopeless

What kind of thing is this?
I used to be ambitious and excited
Butt everything has changed
Oh, I dont know how to overcome it
My brain still try to find way
Shoud I isolated my self far away
If it so, how can I do that?

new version:

I don’t know
Why I feel so alone,
Surrounded by a crowd,
I feel empty,
Like I’m nothing,
And hopeless.

What is this feeling?
I used to be full of ambition and excitement,
But everything has changed.
I don’t know how to move past this.
My mind keeps searching for a way,
Should I isolate myself,
Far from everything?
If so, how can I do that?
