i wish i could speak another language.. I don't feel very good about it lately.
Are you feeling depressed about it?  That could affect your thoughts, behavior and feelings, which may be why you don't feel very good about it.
Yeah maybe. I've been taking more days off work too.
It could just be a  normal temporary reaction to events in your life. Have you lost a loved one recently?
No not really. Maybe I just need to exercise more. Do you think that can help?
Exercise could release the endorphins which could elevate your mood - your depression isn't a a side effect of some drugs, is it?
No, I'm not taking any drugs. Maybe just having a bit too much coffee lately and not enough sleep.
That's a possibility.  Are you restless at all, or do you feel ashamed about anything?
