Recently I meet this girl on an app and for reference I just turned 18. Her profile said she was 17 and I asked her what grade she was in just to make sure she wasn’t lying about her age and she said senior so I didn’t think much of it. She looked like a 17 year old and talked like one at first. 

We started to sext and send explicit photos to each other and while we were sexting she was saying some cringe stuff which made me question if she was actually 17. But then I thought to myself that it’s just my anxiety taking over and that I’ve worried about stuff like this in the past with other girls and they turned out to be the age they claimed to be. So I asked if I could see some proof that she was 17 and she had already told me prior to this that she didn’t get her license yet so she didn’t have anything to give proof.

I was skeptical at this point so I was asking her questions that seemed to be relevant to 17 year olds where younger people wouldn’t really get it. Some of the answers made her seem like she was 17 and others didn’t. I didn’t block her right away because I felt like I had to find out the truth somehow. All the while she still just wanted to sext so I sexted back which is where I think I messed up. I continued sexting her despite my suspicion which is making me feel so guilty and anxious. I did this because I told myself I was overthinking and that why would she lie so I believed she was 17 after all my suspicion.

Then I couldn’t let it go and I told her I had a bad feeling she lied about her age and she asked me if she didn’t look 17 and at that point I blocked her.

I don’t know why I didn’t just block her in the first place or why I continued sexting her I feel so anxious and terrible about it. 

What should I do? I need help.
