You did the right thing, neutrino. That doesn't mean that all the members of your group will necessarily understand what you are going through. Hopefully they will, and I also dare voice the hope that if one or two of them should behave childishly, the others will step in.
But if you hadn't told them, they might have started wondering, or thought there was something else going on. I think that some spectres are best killed by sunlight, if you'll allow me that metaphor.
