I'm going to try and make this short and sweet. I am a 24 year-old male and I've been experiencing BPD-like symptoms for the last few years. I've only recently begun to realize that this isn't normal. Basically, I'm just wondering how to approach a G.P. without sounding like I'm self-diagnosing (although, some self-diagnosis will be expected considering I'm asking about it) and what should I say? Any pointers? 

Also, I'm fairly new to my city and haven't found a new GP and I work alongside a lot of the physicians in my line of work.
