I'm so concerned about the ending that i don't even know the plot

I'll start it off by saying I'm not one for the complaining
You wouldn't know it from my writing
You wouldn't know it from my songs
But I am different, I am free
I am what you need

But oh my God
I miss you more than I thought was possible
I understood the obstacles
But you could have tried more

Because sometimes it seems
I need a mom more than I need to eat
So I didn't eat and I didn't sleep
I'd go all day without a bite
And that's not my fault

And I'll admit sometimes my chest
Gets so tight that I throw fits
You said you'd always be there
Where are you through all of this?
Because this is hard
This is way harder than I thought
I'm so concerned about the ending
That I don't even know the plot
Except for I am different, I am free
I am what you need

So you think of all the things that make you sad
And don't include them in your better half
Because I'm not like you
I don't find happiness in a meaningless existence
I don't know what I'm going to do
But I am different, I am free
I am what you need

And yeah, I believe that there's a God
I believe that there is something out there
Other than my thoughts
I believe it was never science against religion
It wasn't poor against wealth
It was always me against myself
And I'm so scared who's going to win
Because I wake up feeling so shitty
It's been so long since you've been with me
I don't know where this old body's going to go
Or my soul

But I know I am different, I am free
I am what you need
