Whenever I read the Quran I don't feel ease at all. Especially the verses about punishment , war etc
The Quran is written to help the faithful deal with all of this life and the afterlife’s primary issues, which includes war in this life and God’s punishments in the afterlife. Certain chapters of the Quran, such as chapter 9 (al-Tawbah) are designed to be grim because they are dealing with certain extremely difficult situations that the Muslims faced.
What you can do is find which chapters you find inspiring and enjoyable and read those. Some chapters, like Maryam/Mary, are heart-touching without being grim.
And God knows best.
