Jerry, First of all, sorry to hear that you had cancer and I pray that everything is clear now... .keep up the fight against that horrible disease!
I know we've mentioned a number of similarities between our ex's BPD traits and I can relate to what you are saying there... .
Here are a few of the big ones that I had during 4 years:

- She was stabbed in the ovary by a psycho ex, so may not be able to have children again. (when we tried, suprise suprise she fell pregnant almost immediately!)

- She regularly had all the symptoms of Ovarian cancer and she was set to die at 35 (she's currently 31). When we went for numerous check ups during the pregnancy I asked the doctor (naturally as a caring Dad to be) and he carried our tests and examinations and said there really wasn't a lot to worry about.

- She had an eye condition from birth that made her eye look lazy... .it was only noticeable when she wanted it to be (I think it was just a squint!)

- We went to hospital once as she had a lump in her chest... .the doctor said it was just a harmless cyst but for my ex, she decided it was a cancerous lump that may need removing.

- She once rang me to say she was feeling faint, I rushed home from work and she had collapsed and it was as if she had been drinking... .she was kept in a stroke ward (horrific to experience) but all scans and checks revealed no stroke, no seizure and it was just put down to anxiety.

- She had all kinds of self diagnoses conditions, would somehow how various prescriptions (all mainly drugs for treating pain or anxiety).
The thing I found most frustrating was that she would say she had follow up appointments / scans for each of the ailments but then I would not hear anything more and when quizzed, she would say "oh the pains's gone now".
She would also always have to have something wrong if either of her sons were ill, rather that give them 100% sympathy, it had to be a bit about her too, same with me... .I badly broke my arm and had to have a metal plate and screws fitted but got very little sympathy as she "wasn't feeling great either".
I think it's purely for the attention and drama Jerry... .
