Most of the time when praying I cry because of what it said in every verse of the Qur'an. Is that is Makruh?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Crying because of one's fear of Allah while reading Qur'an or during prayer is a highly recommended act, and Allah praises His believers by saying: {And they fall down on their faces weeping and it adds to their humility.} [17:109]
Ahmad, Abu Dawood and Al-Nasai reported from Abdallah Ibn Al-Shikhir that he said: "I saw the Prophet (Sallallahu Alaihi wa Sallam) praying, and some humming like the noise of a boiling pot was coming out of his chest from crying." But, the scholars rule out any sound that might constitute a word of two letters, as such a sound nullifies the prayer according to them.
Allah knows best.
