Too much dark?

I've sorta been writing a lot more dark in what I've been posting, and I'm kinda worrying I'm doing it a bit too much. Part of what I'm worried about is if I'm just telling people about stuff that hurts too much to hear. I've been sharing the kinda stuff I usually avoid reading. I really don't want to hurt anyone, and I'm wondering if I'm doing that by opening up too much. Even though it feels freeing to not keep stuff hidden, it's not worth it, if I'm hurting people. Is there a way of knowing when I've been sharing too much dark stuff?
