Recently I think what we're being asked of is really unrealistic, and I am growing tired of it and I'm done with pretending that everything is okay. What I'm doing is every work they throw at me, I just do it to the best of my abilities.
Now, the higher ups deem it fit to throw a dinner to celebrate what we're doing so far, and I can't just grin and bear it. Since it won't be on the clock anyway, how do I decline the invitation when everyone is expected to attend? I'm afraid I'll just bring the mood down, so I don't want to go.
Update: thanks people, most of you were upfront and frank, and I guess I see the error of my ways, I guess I'll just stomach it a bit more since it'll end soon anyway. Thank you for all your advice.
