It probably is just you being tired. It is not pathetic, we have all had moments just like the ones you are going through right now, where we don't know what to do, and wonder if the pain is ever going to subside.
Do something for yourself, even if it is just a bubble bath. Relax, take a deep breath, and get some rest. If you don't take care of you, you can't take care of anyone else.
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
