We are constantly taught in both in what we read, and what we see on the TV be it consciously and subconsciously, that being unhappy is not normal. Every time we read or hear about how we should be feeling happy, and how we need to go about it, and for whatever reason we aren’t at that moment in time, well, you feel that’s something must be wrong with you. “What’s wrong with me, I should be feeling happy in my life, but I’m not. Every article I have read says all those steps on how to be happy, but they don’t seem to work for me, I am still unhappy.”You come to see unhappiness as some kind of problem with you, with your personality. Something not normal at all. But it is. It is very normal. It is part of every human being, it is a part of you, it is part of who you are. You’ve got to first of all understand and acknowledge that feeling unhappy is nothing but normal and it isn’t something you should be afraid of. It only means that your emotions are functioning well and are taking care of you by keeping you up to date with the truth.
