Basically, bipolar is a condition of 'highs and lows' ... though this is a very simplistic description.

Clinical depression is a condition of 'lows'.

i think you have bipolar, depression is only focused on sad or emotionless feelings. bipolar has a wide variety of emotions

I'm Bipolar Type II originally diagnosed with Major Depressive Disorder. My doc thought due to my mood swings that I may be BP. He had me keep a mood journal for a few weeks. Wow. My moods were all over the place. Hight as a kite and buzzing with life one day, crashing into the abyss the next. At one point, I was so hypomanic, I felt like I was vibrating.

Also, when I am hypomanic, I feel violently alive. Colors pop. Everything is exciting. My thoughts race so fast I can't even keep up with them. So now I am on Seroquel XR, Lithium and Klonopin. I also have Panic Disorder.

Right now I am between ADs. This depressive episode I have been in has lasted a year now. It's extremely treatment-resistant. None of the newer ADs are working so I may be going on an MAOI. I don't know if this helped. But try keeping a mood journal and definitely talk to your doc about everything. Good luck.

thank you guys so much, the link helped also. I am deff. going to talk to my doctor because i think i may be bipolar. I have too many mood swings. Its like a cycle I get mad or sad for no reason. Scream/Cry and then I am ok.

ohh and what is a mood journal? just like a regular one?

Just keep a small or normal sized notebook with the dates and times of day and how you are feeling at that time. Do this daily for awhile and soon you will see your pattern emerge. Write down everything you feel and what's going on at that moment. It doesn't have to be a novel, just little notes to give you and your doc a general idea. Good luck.
