Dark souls remastered ps4 straight dragon sword too weak to carry in one hand what to do?

I started with dark souls remastered for the ps4. And I just got the dragon sword. Only stands there too weak to use the weapon with one hand. What do I have to do now?

Do you have a sign on, because I think you should do that away

Strength and agility levels should be related to the sword how much you need

Either carry the weapon with both hands or level up your strength.

Wear the weapon with both hands, it is not worth leveling up so that you can carry it effectively, as this weapon does not scale with any value.
