feeking weak

Sometimes it feels like the few vulnerable moments I choose to open up about seem very silly to others and they immediately start to tease me about it. And in my head it just feels like this huge thing. And I hate then I try to be open minded about other people's lives but in return they don't even realise when I'm sharing something serious. The irony is that I just share the little stuff just to see what the reaction would be and when I encounter mockery I close right back up. Maybe this sharing thing is overrated and I should go back to old status quo.
