Does anyone ever feel like they're not allowed to be sick?

I feel like I'm constantly hanging on, and constantly hanging on, and constantly hanging on, and pushing my **** aside, and then this happens to this person, and that person's somewhere else, etc., etc. and I can never get a ****ing break and just keep trudging forward or racing to the end of the day or waiting to go to sleep or praying to be left alone...

Or I speak up to someone but I say way, way too much and everything pours out of me for days and I feel like I become exhausting to even the most patient person and I don't even believe they understand me or take me seriously sometimes.

I just feel like I'm never allowed to be sick, but I feel ****ing sick. But I feel like everyone expects me to suck it up and deal. And I do. That's a good thing, right?

I feel like such a mess right now. I'm paranoid, feel like I haven't slept even though I did last night, wanted everyone on the sidewalk to get away from me after leaving work, and basically felt like I was going to have some sort of break in the middle of Manhattan. I almost cried while boarding my train.

And yet I'm fine. No alarms, no surprises.
