I miss talking to my imaginary friend

Okay, I know this is weird, but back when I was a kid I had a couple best friends and one of them was an invisible one, let's call her Lily. She was made up, but she was just like one of us, she was so real to me. And of course back then we all had our own invisible friends, so that was completely normal.<br><br>After I turned like 13 or 14 I stopped playing with my friends. I went into a phase of "I'm growing up so I need to start acting like an adult", so I stopped doing all the things I loved as a kid. Eventually I completely forgot about Lily and I still didn't talk with my real friends that much.<br><br>Last year I made a new virtual friend, let's call her Rachel. I met her on Discord and she was so cool and we quickly became close. But after a few months she just stopped talking to me. I miss her a lot and I don't know what I did wrong. Yesterday I started thinking about Lily and that made me miss her too. <br><br>But the weird thing is that Lily is made up, so where did she go? I made her up as a kid, but then I grew up and forgot about her. So is she still somewhere, with the same personality and stuff? Or did she just disappear into nothing?
