I should

 Be at a gym 

To let you know

 If 

Then

 Well I didn't know how much pain I was really in

Of

 The gym 

Now had you told me

 I first would have wanted a tour 

I'm suspended from a gym

 That I didn't even know I was a member of 

My head aching

 From my eyes hurting 

My eyes have been

 So strained hurting 

I didn't want them to see

 Me crying 

I had to walk a different

 Way after picking up my glasses 

Thank you
