My toes are hurting just reading your post. I have twice broken toes by kicking something. I didn't learn the first time. Of course, it is not just anger that can break digits. I was not careful stepping down from a short ladder. About four years ago I fell and broke and dislocated my right pinky. It did not heal correctly, and as a result, I could no longer play my sax or my clarinet. The finger is crooked, and I would require surgery to fix it.

Anyway, I hope it feels better soon. Next time, kick your ex. He is probably softer than the furniture.
