I got rid of all of my armor with the exception of the torso for my character to move faster and it worked. Now I have to do the Old Monk boss fight and I'll be practically finishing this to hopefully start next week with Deus Ex: Human Revolution (haven't bought it yet).
I'll be definitely be playing Demon's Souls again someday, there's a lot for me to do and see in that game.
Edit: and don't consume boss' souls
Specially the ones from the Tower Knight and Armor Spider, you can get some helpful abilities later in the game with those two. I didn't know that you can get abilities with those souls before and I regret consuming those two the most.
