Are you always fine???

I saw this video today and it really struck a cord with me. 99% of the time when someone asks me how I am, I will say I'm fine or I'm good. I could be having the worst day of my life and I will still struggle to be honest with the people around me about how I'm really feeling. I think I was conditioned into thinking people will only like me if I am happy and doing good and that people will leave as soon as I "burden" them with my problems. I know this is totally unfair on my friends and that I am really underestimating them. From now on I vow to try and be a bit more honest and not always automatically respond with "I'm fine"
