I haven't officially been diagnosed (it's a long story), but I have a very good feeling that I do have BPD since I fit most of the criteria listed in the DSM - V (I study mental health and counselling and have access to the text). 

I have, however, been diagnosed with ADHD because of the mood swings, irritability, impulsive behaviour, etc, (on top of the attention deficits) so I'm prescribed stimulants to get my school work done. They're helpful...until they wear off. Some of the all day medication I've taken in the past has actually managed to make me feel suicidal out of seemingly nowhere, or has otherwise given me a full on nervous breakdown. I'm wondering if anyone else has experience with BPD and ADHD and taking stimulants? They literally make all of my *suspected* BPD symptoms so much worse but going without means I have the added stress of not doing well in school... its a bit of a catch 22.
