well we cant diagnose here, but that type of life certainly sounds like it could contribute to such a diagnosis. have you been evaluated for PTSD? you have certainly been put in life threatening situations. do you have a therapist? i would definately talk to a therapist about the possibility. it could make a world of difference in your treatment.
i tried counseling and meds just addressing the bipolar and never really got anywhere. it was not until i was diagnosed with ptsd that everything came together and made sense. when therapy and treatment focused on that i made great strides in becoming healthy again.
good luck.
