We had a 3+ hour phone conversation and we clicked so well and I felt like we made a mutual connection. It's been a while since I was able to have a conversation like that with someone. 

After that I couldn't sleep thinking of what I said wrongly or what might happen. The whole thing has been occupying my mind the whole day. 

I'm trying not to be hopeful of anything or expect this to turn into a relationship hence I keep telling myself that they're probably not going to text me again and that was it. 

I have the urge to text them first but I also don't want to seem clingy. I'm not sure what to do but I'm also sure I'm overthinking it. 

How can I feel better? Any advice or suggestions are welcomed.
