I’m 15f, recently I’ve randomly lost motivation to just do anything or care about anything. It happens on and off, sometimes I’ll be happy and excited about things and then the moment I start thinking a little too hard about life everything goes down hill. I don’t just lose motivation to do things like schoolwork and assignments, I also lose the enjoyment I get out of things that interest me. My favorite shows and movies seem worthless and things I was excited about doing hours earlier just seem like they don’t matter. Like I said before this happens on and off but it’s been more frequent recently. Is this normal?
