Is feeling anxious in a potentially dangerous situation or depressed in a depressing situation really a disorder that needs to be treated? It seems like a normal response and what needs to change is the situation, not people's reaction to it.
Anxiety and sadness can both be adaptive, yes. How we cope with those emotions can also be adaptive or maladaptive.
Both anxiety and depression, even in circumstances where they are reasonable responses, can benefit from supportive counseling, acceptance, self-compassion, etc. It's important to note that a therapist can "treat a problem" and "support and facilitate". In the second sense, all suffering can be "treated", even if it is not considered pathological.
Isn't this like asking "is it weird to feel ill during an illness"? What I mean - shouldn't humans be able to cope with these situations as "sad", but not "depressing", as depression reduces their ability to move forward?
