Waking Up

What is it about waking up that sucks so badly? Lately every time I wake up, whether it be from a nap or from night's sleep, I feel awful - like an elephant is sitting on my chest and I can't breathe. It's like I'm consumed with this weird sadness or feeling of isolation that I just can't shake. Yesterday was the first time, I think, that those feelings followed me all day long. Usually once I'm up and around other people the feelings will fade, but not yesterday. All day long - there they were. And today when I woke up it was the same thing, only even more intense than yesterday. What the hell is going on? Why do I feel like this? I don't understand. But I do think this is why I have been having such a hard time sleeping lately. I know what it's going to feel like to wake up so I try to avoid it as much as possible. I need to find something to occupy my mind other than me. I've been locked up inside my head for a couple of weeks now and I haven't been able to figure out what's going on in there so maybe it's time to just let it go...if that's even possible.
