For my own part, when I worry about coming across as whining in my LJ posts (which is often), it's usually in the context of not being perceived as tedious. In which case I counter by making my whining entertaining (or trying to, anyway).
Sometimes it's in the context of not wanting to offend people who have it worse by being perceived as attempting a status-grab. In which case I counter by talking about all the ways I'm really quite incredibly fortunate.
Sometimes it's in the context of being afraid people will think less of me. In which case I mostly don't post.
There are other contexts, and other responses.
Which is to say, a lot depends on how I model my audience.
So, in your position, I would start by asking myself who I think I'm talking to, and what I think they are likely to take away from it.
