Cinder, you most certainly aren't worthless. Yes, there are a few people snarking at you, although Tack in particular is a half-man half-snark hybrid who could probably send devastating snarkwaves through the air. But in any case, what people say on the internet should ideally not affect you, if you choose it to be so. Of course, things are rarely ideal; i know my deeply ingrained social anxiety makes it incredibly difficult for me to emotionally detach myself from what people say to me on the internet, and for all i know, you might be in a similar situation, and i am terribly sorry if you are, because i know the pain of it.
What i do know is that you're not destructive to those around you, and people don't speak about you like they'd speak about that bunch of rebellious chavs on noisy scooters who violate every single traffic law without wearing a helmet (i.e. Darwin Award candidates). That's plenty for me to consider you a decent fellow, for what it's worth, and then there's also the fact that you're a pretty cool dude on top of that. At the risk of sounding like a terrible person, i do have a vague idea of why a few people might snark at you, but i'm not going to just throw such potentially inflammatory input at you out of nowhere. If you really want this input, feel free to PM me; just be aware that this is meant solely as a service to you, not a personal attack. I would NOT do such a thing to someone who's feeling down.
