I Can't Help It...

Can somebody help me
'Cause we all know I can’t help myself
My existence is pointless
Like an unread book left on the shelf
Can you give me a reason
To keep this air inside my lungs
Or a shoulder to lean on
To hold me up when I’m not strong enough to do it for myself
But I’ll be honest I’m not as strong as I used to be
I’m struggling
I can’t help it
