I got catfished for four months

About four months ago someone followed me on Instagram. Mutual followers, went to a school nearby, profile looked completely normal. We started talking in DMs and it just clicked. Same music, same sense of humor, similar stuff going on in our lives. We talked every single day. I started to actually like her. I told my best friend about her. That's how real it felt. During those four months I told her things I hadn't told anyone else. About my family. Stuff I'd been going through. Where I lived and what my routine looked like. At the time it felt like trust. Looking back it feels like something else entirely. She said she wanted to meet up. I got there and waited forty minutes. She never showed. After two days of no response I went back through her profile and did a reverse image search on one of her photos. It pulled up a completely different girl's account. Every single photo had been stolen. The person I'd been talking to for four months didn't exist. I went back through every conversation looking for anything real and found something that made my stomach drop. A few weeks earlier she'd mentioned a street near where she lived. It was my street. And I never told her where I lived. I didn't know who this person was or how they knew that. I didn't know what else they knew or whether I was being watched. I was scared and I didn't know who to tell. I realized I couldn't sit on this alone. Whatever this was it was bigger than something I could figure out by myself and the longer I waited the more anxious I was getting. I needed to tell someone real, not just think about it in circles at midnight. Talking it through helped me realize I'd been trying to figure this out alone when it was already bigger than something I could handle by myself. We agreed the best next step was to tell someone I trusted in real life, not to make it a whole thing but because carrying something this unsettling alone was only making it worse. For me that meant telling my dad even though I was embarrassed about how it would look. I wasn't going in expecting him to fix everything. I just knew that having one person who actually knew what was going on would make it feel less like something I had to constantly manage by myself.
