I`m heading for the hills.......... 
Nah, it's just little stuff.
It was based on how you said you'd let some things go around your house. I know that while it's not something that may affect the conscious, letting routine maintenance and stuff get messy and unkempt does two things - it builds up in the subconscious, and it just doesn't feel good to exist in day to day.
I've noticed that simply cleaning my desk and workspace has a pretty profound effect on my overall feeling of well being when I start my day -just creates a nicer atmosphere to exist in.
So, while you're wating on your biopsy (if that's where your're at), I'd use the time to do small upkeep work if you have the time. Every task accomplished actually is good for the pysche overall, and leads to better feeling in the day to day. Plus, doing shit occupies the mind's focus whereas being more sedentary causes the mind to drift and speculate on shit that might not even be true.
If I've misread that, my bad, it was just a thought I had.
