I think we have to forget about "normal". First, because we do not really know how other people feel inside. We just see their "persona", a facade. Also, because "normalcy" is not an univocal term, it can mean many things, it is ambiguous and very tied to cultures and historical periods. And for many other reasons I do not want to mention or discuss here not to bore you.
But, you are right. We have a condition (due to whatever reason) that impedes us to enjoy life in the way we think we should be enjoying. I believe that there are several tools to help us to enjoy life better. We need to try them and choose what is suitable for us. I think we can be able to enjoy life, maybe temporarily and periodically, with the appropriate support and commitment.
On the other hand I think that there are too many stressors, cultural mandates, market pressure, etc, etc, that are conditioning us. Part of the solution of depression is within society and external to us. I think if possible we need to engage in some activity to change the status quo somehow because this society is sick and sickening. In the meantime, we need to better develop coping mechanisms to face those society shortfalls. It seems a lot. But we are not alone. We have each other and it is good to have a platform like this, to help each other.
