I have a few questions I would like to ask. I have read books and articles on BPD and he seems to fit SOME of the characteristics as well. Also, he is currently taking Neurontin and Wellbutrin. I know that some antidepressants can actually trigger mania. Lastly, I heard of something called Rational Emotive Behavioral Therapy.
Many psychiatric diagnoses overlap in symptoms.
Thus, he may be bipolar or borderline or both. Hopefully, his doctor's treatment plan addresses all the aberrant behaviors your friend has. Wellbutrin has a reputation as a good medication for bipolars with a low incidence of inducing mania. It is not, however, free of any risk of inducing mania. If is a form of cognitive therapy, and seems to work well and is easy to do in real life and apply to real life situations.
