If your having a really really hard time turn down the dificulty otherwise yes a follower is a good idea (but a dog too won't really last long) keep you attacks focused on one until it drops, if you can conjure a creature to help take the heat off you and use any resist fire and frost potions you have. If your a mage maybe use shock magic.
With patch 1.9 you can level up indefinly. When you get to level 100 with any skill you can make it legendary. It resets your skill level, gives you your perk points back and lets you get every skill in the game
