Perhaps it helps to understand that a spectrum can be comprised of a cluster of continua: a possibility space of which any subset can be observed. Like each colour in the light spectrum. The continuum notion in that case can refer to its brightness. Same in the case of emotions. We don’t just experience one emotion at any given time although there’s a prominent one and others might be subdued.
How we cluster certain aspects, such as traits in mental health as well as the threshold to diagnose anyone is of course arbitrary.
Severities in presentations are perhaps seen as a continuum, but the underlying structure that aids in defining it, is a spectrum.
