My worst fear is that I’ll get really depressed. This is because I started taking some anti-depressants once which gave me a terrible adverse reaction and I don’t want to take anti-depressants again for fear this will happen.  Recently I took some antibiotics which can make you feel down, and a week after I finished them I’m working myself up into a frenzy that I’m depressed all of a sudden. I feel quite down but I don’t know if that’s because I’m constantly thinking about it. Can anyone help?
