If you haven't gotten the elemental resistance enchantments on your armor, you should look for just about any magical group. Being Nord, you'll probably be able to deal with necromancers (frost resist) but conjurers should still be able to rip you a new one.

Draugr Deathlords should spawn like crazy at your level, imagine a room full of dead guys swinging Ebon equipment all shouting fus, ro, DAH! at you. If the game allowed for malleable walls, you'd leave an imprint.

If you really feel like dying, try to beat the Greybeards.

If you're really bored, ditch the armor and weapons, don a mage's robe and rely on alteration for armor and destruction for damage. Or, if that doesn't sound like any fun you can switch to the armor type you are not using and use two handed weapons.

Finally, you can always turn up combat difficulty in gameplay settings.
