I'm unsure.... I mean I guess we all have insight even if it's just slightly if we have had bipolar for years and are in therapy. I guess for me I like the hypomania so don't really bother about symptoms and looking out for it. But can sometimes "catch" the symptoms of mania if I'm being honest I chose 9/10 times not to listen to my inner sensible thoughts though. I'm quite ignorant when it comes to my symptoms cause I believe I'm misdiagnosed and don't have Bipolar. I will blatantly lie to your face even if I have sever symptoms like delusions, hallucinations and paranoia.
