Revised Text:

I haven't felt a deep, consuming crush in years. I thought those intense feelings were a thing of the past as I got older and experienced more relationships. But last week, everything changed.

A close friend's relative visited and asked me to show them around. During those two days, I unexpectedly developed a strong crush on that girl. It was the first time in ages I've felt such a connection with someone.

I was so into her that I'm starting to regret not making the most of our time together. Plus, she followed me on Instagram after the first day and we started texting, but I feel like I messed up some of our conversations.

Now I'm feeling a mix of sadness, worry, and anxiety. I'm disappointed in myself for not being my best self, scared that I might not find someone I like as much again, and unsure about how to proceed with her.
