TIFU by accidentally sending my boss a private voice note meant for my friend

I'm a 20F college student juggling classes and a part-time job at a small café. My boss, Mr. J, is a nice guy but can be a little too particular about rules and routines. Today was one of those chaotic shifts where everything seemed to go wrong. The coffee machine broke down, we ran out of almond milk, and a customer yelled at me for getting their order wrong. By the end of my shift, I was beyond frustrated and just wanted to vent.

After clocking out I recorded a voice note for my bestfriend, ranting about my day. I complained about the entitled customer and even made a snarky comment about how Mr. J micromanages everything. It wasn't anything too cruel, but I definitely called him "Control Freak" at one point.

Here's where I messed up. I sent the voice note... but instead of sending it to my friend, I accidentally sent it to my boss. I don't know how I managed it, maybe it was my tired brain, or maybe I just didn't double check but as soon as I realized, I felt my stomach drop.

I panicked and tried to delete it, but it was too late. Within minutes, I got a message back from him saying, "I think you meant to send this to someone else?" I was mortified. I apologized profusely, saying I was venting after a stressful day and didn't mean any disrespect. He hasn't responded yet, and I have no idea how he's going to handle this.

Now I'm dreading my next shift. I don't know if I should bring it up again or just hope he lets it slide. The café is one of the few places near campus where I can work flexible hours, and I can't afford to lose this job. I keep replaying the situation in my head, wishing I'd just typed a text instead of recording that stupid voice note.

TL;DR: Had a stressful shift at my part-time café job, recorded a ranting voice note about my boss, and accidentally sent it to him instead of my friend. Now I don't know if I'm getting fired.
