I felt the exact same way about BOTW & event took numerous sessions over 5 years to beat it. My best advice is to invest in health upgrades & then find the Master Sword as it has a recharge period after it "breaks", so you rarely need to use your other weapons & can safely use your good ones & just keep one of each elemental type weapon in you.

This changed the game & made me finish it without interruption after getting it.
