Dude just try to be happy. I'm making a point separate from the post.

Where is this? I smell a road trip (and smoke)

In the strict context of the post, I absolutely agree with you. To say that positivity or trying to encourage someone to be happy is wrong universally feels equally dismissive.

TLDR: Looking on the bright side =/= 1984 forced happiness.

Obviously grieving someone's death or mourning a loss is a process that needs to be gone through, you're taking a generality and extrapolating it into an absolute truth.

Should you grieve your mother's death? Yes, that's horrible. Should anyone else tell you how to feel about that? No, they should f*** off.

Should you continue to be sad and grieve for years on end? Past a certain point... If you can help it, no. Seeing the positive and being thankful for the good in things will make you a happier and better person overall.

Someday my mom will die, and it will wreck me. Hope not painfully, I hope she doesn't suffer, but it's going to suck a lot. And it will suck after. But I hope that I will remember her for the positive moments after some time has passed.

The post asserts that trying to look on the brightside is actually wrong if you're not feeling good in actuality. It completely misses the point that sometimes changing your mind is a good thing, and you can often be a buoying force in someone else's life

Agree. Positivity isn't about minimizing something, it's about being generous with your ability to spread.happiness, and realizing that happier self-talk and "faking it" leads to more actual happiness.
