life chart bipolar

Does this sound like bipolar disorder?
My therapist says she wasn't sure if I was suffering from bipolar disorder or severe anxiety or simply depression. Last week, I was not happy lists and felt like I was almost bouncing off the walls of energy. I literally felt I could do nothing. But this week, I feel so sad. I woke up this morning and I just brust no reason to mourn. I feel I have this empty space in my heart. Now I still feel like life isn't worth living. This comes almost every couple of weeks. Do you think you bipolar?
First, if you're watching a therapist, given time to correct diagnosis. She can do this better face to face than anyone on this site can. He has also tried to keep a diary of what and how you feel, so you can share with your therapist next time you go? There are a couple of good sites you can go for information additional. DBSAlliance.org-has several self-help test you can take and then take your therapist. Also another good site is NAMI.org again with a lot of good information. Then, finally, there is a good publication, which also has a website, called bphope.com. But the end result, if you are investing time and money to see someone, give them the benefit of the doubt and let him help. Are you currently prescribed medications.
