Ok so I've never done this before, I've never talked about this to my family or friends, but I need some advice before I can continue forward,in deciding if this is just normal or something I may need help with.

Ok so for as long as I can remember I've been having conversations with people sorta in my head. Like I'll imagine that they are right in front of me and I'll ask them how their day is going , or I'll bring up old memories of stuff we used to do, or I'll ask them questions about stuff i already know the answer to. but I'm completely alone just talking to nobody. I'm honestly really nervous I've always known that this was weird but it really hit me today.

Also I just turned 20 as of dec 13th if that helps any
