I'm much the same. I find it so hard to let anyone know that I don't feel good. It took me 6 years to see my GP about my depression and my family didn't find out for another 2 years after that. There is something in me that stops me being open about how I feel and I'm yet to work out what it is. I just know that whenever someone asks me how I am all I will say is "I'm alright" even though that is normally far from the truth. It's something I need to work on, but it's hard.
