trying to watch what I eat
I found your problem. You are "trying" to watch what you eat. Don't try, just do it!
I know, I know, easier said than done, but I absolutely swear by logging all of my food. Like NCNOLE said, it is really easy to have a distorted perception of how much you are actually eating when you are not logging it.
Someone who is busier than you is working out right now.
There will come a day when you can no longer do this. Today is not that day.
