Am I ready for Blighttown?

So I’ve spent all day grinding in the depths for humanity and souls to buy moss from the merchant. Got the claymore +6, the spider shield, and the elite knight set up to +3. I heard that you can farm large titanite shards down at the bottom of Blighttown, but I’m currently at 10 soft humanity (maybe that was a mistake) and would rather not lose it. Am I cooked?
