A lazy boy

it is the end of July and I am horribly sick like i have been standing outside in the rain for the past twelve hours...baha! I went and "volunteered" up at a summer camp for two straight days; in reality I just sat and lounged around the pool for two days working on my tan and fattening up on great camp food. I am pretty sure that I got this sickness from/for two reasons:
1.i have been running non-stop this summer. I have been busy ever since and before I got this job at the theatres. it has been fun, but not a lot of rest and sleep has come due to it...so when I went up to camp, I am pretty sure that a sickness was just waiting to sneak up on me. I have heard that somtimes when you are super busy for a long time, and then slow down, your immune system slows down a bit and lets down it's defenses. No idea how scientific that is, no qoutes please.
2. I was living with eight other guys during this stay and one of them was quite ill, while two other boys were either getting over sickness or surrendering to it's grip.
Other than this sickness, i am doing very well.

I have realized something.
I am very weary of saying that I am good, when I actually am doing very well. I always feel as if, whenver I am good, the slightest movement will trigger a landslide of pin drops that will be my defeat. I feel that most times I am not allowed to feel alright becasue others elsewhere are having bad ones. I thikn that if I admit I am having really good days, God will just take them away.
I have things to definately be thankful for, but I think I have forgotten how to be joyful for them. Is it a sin to be scared of a reality that I am not used to?

thankyou.
