Alya, I think sometimes people who know us best can see through the fake smile and sense something is not okay with us, but they don't want to intrude but wish they knew how to help...
We are never alone. I think we all have a well or deep recess inside us and sometimes we feel down or sad for a good reason. I try to express it in words through my poetry. I try to make sense of the thing and try to understand it better. I may not find answers. But I usually end up seeing more of the bigger picture. Writing poetry makes me...um think. LOL. I should have said that in the first place. ^_^
It's not always possible to fix the thing, whatever it is. But telling someone can help. Tell a good friend.
Hope someone hugs you today. :)
