For a newbie, yeah, downvotes mean a thing because it's like you're not doing well or you did something wrong.
But don't mind them. Whale wars and you got hit by the stray bullet.
Don't worry too much about it. I think the DVs you got are 0. And I see your rep is still 63.
Just continue what you've been doing til now and you'll be okay. You're already doing well actually, being here for 3 months with all these acknowledgement and hardwork is already great for a newbie!
