What must one do with people who cause one to feel doubt, lose peace, become frustrated, and experience self-contempt? And to what extent is architectural engineering suitable for men, given the student's feeling that it lacks blessings and negatively impacts thinking?

A Muslim should be optimistic, have a good opinion of Allah, and be strong in heart and soul, avoiding despair, pessimism, and obsessive thoughts. The discerning person should choose righteous companionship that aids them in their religious and worldly affairs, and stay away from bad company. Architectural engineering is one of the communal obligations (fard kifaya) that the Ummah needs, and a Muslim will be rewarded for learning it with the intention of benefiting Muslims. As for the lack of blessings in studies, this may be related to the student himself, not to the specialization. The absence of the religious aspect can be compensated by seeking sacred knowledge outside formal education, and envy is not exclusive to engineering. Advice on these matters is personal and relates to the inquirer himself.
