I think Helen probably really is frustrated that everything she says and does seems to get jumped on. As pointed out, this doesn't happen with everyone and a more popular celebrity might not get treated in the same way.
I think she hopes to show us what she's really like. Contrary to what she thinks, though, I don't think she is very intelligent or deep, and I think she is rather thoughtless in some of her acts. But I don't see any evidence that she is deliberately unkind and I do think she seems rather vulnerable. I think she'd be better shutting up for a bit and getting herself together in private, and care a bit less about what strangers think.
