What should I do about my inability to work due to an illness that causes others to mock me, and the resulting psychological harm, which compels me to leave my job and spend from my capital for fear of it running out?

Tips for dealing with mockery at work: Seek Allah's help and ask Him for assistance and steadfastness, and recall the hadith "The strong believer is better and more beloved to Allah than the weak believer," and what it contains of encouragement to be keen and seek Allah's help. Remember that the mocker is gifting their good deeds to you, and consider the situation of others who are in a similar position to yours. Seek the help of trustworthy colleagues to advise the mockers, and look for another job if the matter does not cease.
