I think the reason some people might think you're depressed is even though you show both themes in your music, its not a warning sign when someone is happy, especially completely happy, but when they see any hint at someone not being happy it points towards a more depressed person. like if you go skydiving all the time and never fail but then your parachute fails once, thats the end of it and I think people just want to be assured that your parachute hasn't failed yet
are you saying that anyone who acknowledges anything other than complete happiness 100% of the time might be depressed
