Don't try to build an archetype.
Walk out of Helgen and use the first thing you need to. Just go from there.
Building archetypes in Skyrim is fruitless. The game is designed to push you everywhere and no where.
Indeed. A good advice.
If you do want to go for an archetype you may try the crusader.
One melee skill, heavy armor and restoration.
Divide health magica and stamina about equally. That should give you enough offensive power with powerattacks, decent healing capabilities and enough health to fight in melee, but not enough to be a tank type.
