One more day

Actually a pretty good representation of depression and anxiety medication

This immediately reminded me of Adventures with Anxiety, a browser game about living with Anxiety.

It's very well done, and simultaneously funny & serious.
- Thanks, that was really useful

He still doesn't look happy

Pills don't magically make people constantly happy. But without them it's barely possible to be happy in the moment
- For me, they made me feel nothing even when I should feel something. My heart goes out to anyone going through this.
He still needs time to catch his breath. It’s like how getting a single good night’s sleep doesn’t leave you fully rested but it’s still important to do.

The first few steps aren’t “get better” but rather “stop feeling worse”.
Antidepressants aren't a silver bullet for mental health, they only bring you closer to your (healthy) baseline. The most difficult barrier to a healthy change for mental health is our obligation to waged work, and in some cases are the cause of poor mental health.
Well, it is a black dog. Keeping it at bay is often the best we can do.
He doesn't habebthe direct pain of being chewed on, but the beast lingers there waiting for the pills to wear off.

Of course they aren't happy.
- Hey, someone other than me constantly hits b instead of space too. Nice.
I think that's the point.
That's because it's a pill and not a joint, perhaps.
Because the cure is illegal.
That’s because he killed death with pills, apparently, and now he became death himself, as it can be noticed by black clothes in last panel. And it is hard and ungrateful work to be a death. Why would he be happy?
- The comic is about depression, not death.
  
  He doesn't look happy because the medication doesn't magically cure him.
  
  All they do is temporarily quench the longing to die. At least sometimes. The other times they just help you to fall asleep before you fall apart.

fake, the doctor didn't tell him the dog was all in his head

To be fair, mental illness is all in your head. Because head broken.
- Depression or whatever doesn't mean you're broken per se, but yeah. In a perfect world your doctor would be able to acknowledge that the brain controls the body.

Dude just train your dog not to bite.

What the fuck is a metaphor?
- It's for metaing these nuts
  
  I love that Google is so absolutely trash now that when you Google "What is a meta for?" it just assumes you're a moron and refuses to even consider the possibility of throwing up a blog of dad jokes that includes that exact line.
  
  This joke exists, Google, I know it does. You will not be spared.
  
  Edit: DDG got me
  
  What's a meta for?
  
  Nothin! What's a meta for you?
  
  This is apparently a Christian joke that I do not understand, that or a meta joke about another set up about "What is a meta," but DDG found it, dammit.
My little velvet hippo pippo doesn’t bite, it consumes.
