I'm glad you don't find it mean. Just that a fair few mental illnesses have overlapping symptoms as well. Like, pretty much everything you said could JUST be PTSD, instead of being PTSD with a cluster of other things, and BPD has a bunch of similar symptoms to BP2, SAD could explain why you feel BP2, and so on, so forth. Maybe when you see your doctor, make sure to talk about your feelings, and try to avoid them catching on that you've done your own research, or else they may think you're exaggerating, or looking for drugs. Trust me, talking about your feelings, and saying how you feel concerned about your mental well-being will get you further than saying "I searched Wikipedia and found I may have this, that, and the other". You know?
