As of late, my life is becoming more of a mess, because of none other but myself. I used to be very driven, and in-control of my behaviours. I was well-planned, disciplined, loved to read, and loved to discuss things. Now, things are completely different. I'm becoming lazy and aversive to introspecting or thinking too much. I lack discipline, and my attention span is suffering (I can't even sit down to read some of my favourite books). It feels like I'm coasting through things without actually being fully aware (you know that feeling when you know something inside out? I don't have that anymore regardless of how much time I invest). I'm just not ambitious or driven anymore. Consequently, many of my life-aspects are suffering (academics, home life, friendships, etc.). I used to write things down whenever I went through a rough patch, but now I can't even bring myself to pick up a pen.
Someone told me that I might be depressed, but I don't think so: I don't feel anything at all. Has anyone gone through something like this?
