I am a musician. I work in places that serve alcohol. I do not like this, but it is impossible for me to maintain my family by doing another job. My parents have the means to help me financially but they avoid it for some reasons. What do you suggest me?
Try to do another job. It is never impossible to do another job and still make a living. You can manage it if you really go for it. Otherwise, you’ll be distressed by time as the devil will push you to worse conditions and mess with you that you do some other wrong stuff.
You can still earn money from this until you find another job. Your earnings will not be unlawful as you are in a state of necessity. Though we cannot say the same if you do not make an effort on finding another job.
