You're not happy because you cannot be you in this society.
Well, I'm not sure what 'this society' is in your context, but I live in the UK and spend quite a bit of my working time doing things for people in the USA, so I'd say I'm probably in the same society as you. If you can't be happy in this society, then I think it says more about you than about society in general.
"This society" applies pretty much to most 'civilized' societies in the World, where people have laid down rules against individuality and self-expression for the sake of maintaining order and economic stability. You have only three choices. 1. Don't fit in and struggle outside the society for your own sake. 2. Fit in and pretend everything is cool, if you are lucky enough to do so. 3. Fit in and suffer because you cannot pretend everythig is cool. I'm sure there are nuances in-between those options, but you get the idea.
People can't really be happy in this society, except in the way prescribed by the society itself, which is not really happieness but self-satisfaction. If they did a good job of fitting in, they would be rewarded with success, money, friends that accept them, bosses that praise them. That can make them feel better about themselves, and they might think it's happiness. Consumerist societies make the best of these ego-boosters to give people even more illusion of happiness, and they will fight hard anyone and anything that doesn't agree with how they see "happiness" because their version of happiness is cheap and readily available, and nobody would give that up. (Note that I don't say 'corporations', but 'society'.)
