So, I’m about to lose it.

I have a Canon EOS 4000D. I bought a Canon macro lens (EF-M 28mm) which turns out isn’t compatible with my camera. I bought a mount adapter because I really just wanted the lens to attach (EF-EOS M), and it fits my camera but not the macro lens. Today, I received a lens mount adapter (MD-EOS) and that also fits the camera but not the lens.

WHAT IS UP WITH THIS LENS?? What did I buy? What should I have bought? I feel really stupid, and I really, really just want to take some damn praying mantis face closeups.

Please help. I have, like, $1,200 worth of equipment that’s effectively useless for me right now.
