don't worry about that. There's a lot of brave facing going on at the moment with "we're all in this together", "we've all got our challenges", "it's tough but we just have to keep going" being bandied about where the "it's ok to talk" is in typical human fashion resulting in people pretending they're fine to not be the one who looks weak or seen to be complaining when most people are just bottling up the same emotions.
This is a platform for you to air your grievances and feelings and it's alright to do so, you're not fucking up the thread at all and you're right to share and get it off your chest, even if unfortunately many of us don't have an obvious solution. Your problems and issues are important and don't let anyone's actual positive mindset or brave face put you off expressing them. You're only seeing what they're all willing to post about their lives.
