I should be happy

Today was a good day
  like objectively a good day
  like, on paper, a good day

I should be happy
Today good things happened
  better things than yesterday
    or last week
    or last month
    or the last 6 months

I should be happy

But why do I feel like I'm moving my feet through water just to slow them down?
Like I'm looking through cotton just to see where I'm going
Like I'm laughing to prove my smile is bigger than it is
Like even breathing is made harder by the sheet over my lips
  parachuting into my mouth with every breath.
I swear

I should be happy
