You say you have situational anxiety. Does this mean something happened that is stressing you out and normally you're not an anxiety sufferer? Because if that's so, I'm not so sure going on an antidepressant is the best course. They're not the easiest things to take or to stop taking. Therapy and learning coping techniques might be the better bet if this is a one and done situation. Also, do you exercise enough to make yourself tired? Have you ever tried meditation -- it can give you extra energy as well as relax you overall so you're not napping all the time, though I don't really see that as being all that bad a thing.
I have another question.(I'm applying for FMLA right now) I don't sleep well enough at night, so about 3 hrs. after getting up I'll go back to bed for a little while so I'm not so tired. I take a nap after lunch so I have more energy in the afternoon. I'll try to take a short nap around 5 so I have more energy for the evening. My fiancee' is not happy about me doing this. Am I wrong in doing this until I feel better?
