TIFU by lashing out at my work buddy

I recently joined a new workplace and have a crush on a girl in my team. We’re trying to be friends. I share a desk with my desk buddy, who is good friends with my crush. There’s also another girl who’s friend to my crush. I’m not sure, but I think my crush might be seeing someone outside work or may have a crush on my desk buddy.

The three often hang out together during coffee and lunch breaks. I’ve been trying hard to join them, and today I asked my crush and the other girl to join me for lunch, but they politely declined. So, I ate with other colleagues. While eating, I noticed the trio at another table and felt jealous. I wanted to talk to my desk buddy about it but didn’t.

Later, my desk buddy tried to take a funny photo of me, and I lashed out, telling him he didn’t have my permission. I’m uncomfortable with random photos, especially with concerns about privacy and AI misuse. My crush noticed and didn’t talk to me for the rest of the day.

After work, I apologized to my desk buddy and asked if we could talk. He said he didn’t understand why I was upset and was hurt by my reaction. I admitted I could have been more polite.

I messed up by lashing out and upsetting both my crush and desk buddy. Things feel awkward and beyond repair right now, and I don’t want to talk to anyone at work. I just want some sense and strength to handle this.

TL;DR: I have a crush on a coworker who hangs out with my desk buddy and another girl. I tried joining them for lunch but got turned down, which made me jealous. Later, I got upset when my desk buddy took a photo of me without asking, and I lashed out. This upset both of them, and now things are awkward at work. I’m struggling to handle it and want to make things right.
