What's wrong with my body?

I now have the body of a five year old boy hyped up on sugar or a frail senior citizen. Either way, I can not sleep very well anymore. Since coming back from HK I have not been able to sleep past 10 and today I even woke up at 8:13. This is horrifying especially since I have been known to frequently sleep past 1 pm. I love sleep!!! :(

Also, I've been focusing way too much on my legs in the gym. This is because I feel awkward lifting free weights in front of the giant mirrors. I often end up running for 20 + minutes, doing crunches, and then alternating between all the leg machines. I don't want thunder thighs!! lol
