I couldn't begin to tell you why your depression does this (I'm not a professional ), but I do want to say that mine fluctuates, too. It's normal.

I definitely agree with Emily. Keeping a journal can really help you figure out what's going on with your differing moods.

I'm going to have to disagree with Tom on this one. Your mood may not permanently revert to complete normality with time. Depression is an illness that is theorized to be caused by a chemical imbalance, and time doesn't always fix things like that. Getting professional help from a therapist, counselor, psychiatrist, psychologist, or other mental health professional is probably your best bet at feeling normal and happy again.

When I'm feeling particularly low, some of the alternatives can help me get my mind off of it. Going for a run, talking to friends, or doing something with my cats are things that seem to help me the most. Maybe you could try some of these before you can get things rolling with a doctor.

If you want to talk or vent, you can always PM me.
