Are the funds spent on traveling for prayer in the mosque considered extravagance, and are acts of worship accepted when restricted by psychological, not religious, conditions, and is it better to stay in the city and not go to the mosque or to travel to perform more acts of worship?

Prayer in the mosque is not obligatory; rather, what is obligatory is the congregational prayer (jama'ah). So, if you pray in congregation in your home, you have fulfilled your obligation. You must strive against yourself to overcome your phobia, even if it means consulting psychiatrists. Your travel is not considered extravagant unless it causes significant harm to your finances. What is best for you is that which is most beneficial for your heart and most helpful in fulfilling Allah's rights. We advise you to seek treatment, for if you are cured, you will achieve your goal of staying in your home while still earning the reward of praying in the mosques.
