I'm always feeling that people can see it - the pain behind my eyes, fogged out feeling, depression, exhaustion, vision issues, etc. - but usually I don't say anything. When I see my parents I ask them if people can tell how "off" I am - I am so paranoid about this - and they always say you can't see it. I feel like the walking dead - I know people can see how tired I am but they have no idea what is really going on inside.
