What's the difference between the depressions of the bipolar disorder and clinical depression?

Does it really exist one?
I mean, I know that the bipolar disorder have mood changes very often and that clinical depression is more like staying like that most of the time, but isn't kind of the same after the clinical depressed has gotten trough it?
Thanks

Absolutely there is a difference, bipolar people are fine whilst they are on their medication, unfortunately, they think oh, I'm better know then go from one extreme to the other, with clinical depression, its usually a dark hidden secret that they feel that they cant share with anyone cause then they would have to face it and thats their worst fear, there are many types of depression, inability to cope with day to day life, the black hole that you feel you are being sucked into, but hang on for dear life, then their are those who just let go, medication can helps, but dont think that it can go away quickly, its a long haul and can come back again (although usually not as bad as the first time) at anytime, their are usually triggers that set us off, and we often dont know what they are, anyway, thats just whats happend to me or around me, hope this helps, goodluck! :)

The depressive side of bipolar disorder has the same symptoms as clinical depression but the mania experienced with bipolar disorder is a lot more than not feeling depressed anymore. Like you said there are the mood changes or mood swings from high to low with bipolar disorder.

The mania side to bipolar disorder is just as disruptive and extreme as the depressive side. Instead of feeling constantly sad and tired, you will feel very happy with a lot of energy. This may sound good, but it isn't. These symptoms are very extreme and disruptive. They also come with feelings of aggression, agitation, and distraction. Although you may feel great, you can actually be causing a great disturbance in various aspects of your life, including your career and your relationships.

With clinical depression it can presist for years. There is no real reason for the depression and it tends to show up on a regular basis for the majority of the person's life
