I too when I first came was upset at loss and such, but all this tips wise. As soon as you can buy a horse with saddle bags.
You can keep items there. The horse does not have to be expensive. Store as soon as you can extra suit or armor or at least a basic suit of clothes, spare weapon,shield etc. Even if you do not ride its easy access storage.

Store a duplicate if possible in the vault chest. Home owners first thing to do is make at least three copies of your key. One on you, one in your horse and one in the vault.

Try and keep the minimal on you so if you do fugue you can grab quickly.

As mentioned best to run and live. You can alaways go back to finish the quest.

Also when you can do buy portal stones.
