What is causing you to be depressed? Is it just one thing? Could you fix it yourself? If something in your day caused you to be depressed, then it is your own brain, but if it is out of nothing, then it probably is because of the medication.
If the doctor said to tell them if you get depressed, I advise that you do. It is not smart if you wait it out when the doctor told you specifically to tell then if you are depressed.

Yeah, I am back. I didn't last long did I...
Contrary to popular belief, I DO have a social life.
