New With A Question - Sorry, kind of long

I'm new here and have a couple of questions.

I've been seeing a therapist for about 6 weeks now for what I thought was depression.

I've been going through a seperation/divorce for 6 months now.  I had an affair (one of many) on my husband and this time I decided to leave him.  He's an alcoholic and has just started recovery.

During the time of our seperation, I moved to another state to be with my bf.  During the short time I lived there, my husband would call me and ask me to come home.  I would tell him how much I loved him and that I'd come home and I'd go back and forth and back and forth on who to be with...boyfriend or husband.  It was horrible.

In January Dr's found what they thought to be a cancerous tumor in my leg.  I moved back with my husband but continued my relationship with bf.  Husband was fully aware of this.

I've been playing both sides of this and finally one day, I just broke.  I went to see a therapist.

My therapist told me that I'm Codependent.  I read Codependent No More and agree...I am very codependent.  She also said I have signs of OCD.

Then, last night she and I were talking about personality disorders and she told me that I show signs of BPD and Bi-Polor.  I've read what I can on these and identify more with BPD due to the numerous affairs and chronic fear of abandonment.  I don't identify with many of the bi-polor signs.  What I do identify with is the racing thoughts, and moving from one idea to the other.  All of these, codependency, bi-polor and BPD list difficulty in decisions as a symptom.  I've also read that rape as a child can also be the reason for irresponsible sexual behavior, I was raped at 7.

I guess my question is, what's the difference?  What's a key sign of one that seperates it from another?

I'm a successful business woman who feels that I just got caught up in these affairs and always sought approval from others due to a lack of it in my childhood.  Now, I feel like I'm losing my mind because of all these "disorders" that are being thrown at me. 

Any definitions would be helpful.

Thank you-

I am sorry to hear that you have been having so many problems, and I hope that you will get the answers and help you need. Before being diagnosed as Bipolar I did a lot of research on my own, and there were several possibilities that I thought fit me. The two symptom descriptions that I fit perfectly were Borderline and Bipolar Disorder. I have heard that Borderline can only occur along with another type of mental disorder. I am not sure if that is true, but I have read and heard that. From what you describe as your symptoms, Borderline does seem like the most likely based on what I have read, even though of course I am not a doctor and can not diagnose you. A website that helped me tremendously was wrong diagnosis.com. When you research a disease or disorder, it gives you lists of symptoms, possible misdiagnosis, and disorders that share similar symptoms; a symptom difrentientel. Here is the link to the bipolar introduction and bipolar resources: http://wrongdiagnosis.com/b/bipolar/intro.htm

Another thing that may help is for you to take the mood disorder questionare that can be found by searching on google. The test is used to assess Bipolar symptoms and tendencies. I hope that all goes well for you and that the website may help. Keep us posted!
