Filling up empty spaces...

I just realized something. Most of the things in my life are just temporary patches for all the emptiness in my life...the concerts, the video games, the parties, the occasional drinking...everything like that...is just a temporary fix for a bigger problem...I'm at the point in my life where I don't even know what the hell that problem is though...is it that I'm lonely?...Is it that I'm depressed?...I really don't know what the problem is...
