Many people have difficulty dealing effectively with sadness in their life, more so in these stressful times. And left as-is for too long, it can drag one into depths that bring things to a stop. Yes, you can feel sad. Yes, you can - and should - seek help.
Most people do have friends and family and therapists and ministers available, but if they are not being open with those resources, or themselves, little progress can be made. Maybe this has been a lifelong pattern with them too. Maybe they see it as a 'competition', as Piglet suggests. Maybe it's a reluctance to face themselves, maybe it's pride, maybe they like the attention it brings - I don't know. Hopefully, this will give them a new perspective.
