Michelle,
The feelings you were experiencing may very well be associated with lack of food. You could try just eating very small meals or snacks, just enough to give your body some much needed fuel. If the symptoms don't subside, definitely see your doctor. I understand how you feel about hoe people are perceiving you due to your "depression", we are here the the DC, voice your thoughts and concerns to us, we will listen!!
Take care,
Susanne
