How do you tell someone (no one here) that they're genuinely a drag to be around because they're so consumed with how goddamn sad they are that, while they're in your life, you feel like you're being guilt tripped every time you try to do something fun with them to cheer them up? Like you can't talk about anything good in your life, because doing so is just gonna make them talk about everything terrible in theirs?
But like. Yknow. In a polite way.
