Those days you don't want to talk and just want to be by yourself, when the world looks grey but it is okay when you feel a bit down. Today is one for me and for some reason everyone around me think they need to "make it better".

Do I really look that sad, when I just want to be alone.

All is fine I just want to be alone!

How do I tell them "All is fine I just want to be alone" with out them feeling guilty or trying to cheer me up?
