Don't be afraid. Human birth is full of suffering and one has to endure everything patiently, taking the name of God. None, not even God in human form, can escape the sufferings of body and mind.
Even avatars, saints and sages have to undergo the ordeal of suffering, for they take upon themselves the burden of the omissions and commissions of ordinary human beings and thereby sacrifice themselves for the good of humanity.
Difficulties come, but they do not last for ever. You will see that they pass away like water under a bridge. The Master (Sri Ramakrishna) would say: "At the time of death I shall have to stand by those who pray to me".
One should not hurt others even by words. One must not speak even an unpleasant truth unnecessarily. By indulging in rude words, one's nature becomes coarse. One's sensibility is lost if one has no control over one's speech.
Spiritual practice means to keep the mind steady at His lotus feet and to be absorbed in His thoughts.
