Welcome to both of you...
Drakenyte: I definately agree with those who suggest seeing doctors... if you are not ready, try to find out as much as you can about depression and bipolar by looking on information websites... there are also some self tests that you can do online. I really like the "blackdog institute" website for info on both depression, bipolar and treatment. They also have online education programs.
Mike: welcome, it is great that you have come to PC, I'm sure that you will have great insight to share about your experiences and hope that you can also get support and help from the PC community.
