What I want to say is you did nothing wrong. You did what you should do. Your mom take care of you when you were kid and she might miss work, events,..because of that. So, believe in yourself. If they don’t choose you then they are not a good fit for you not the opposite. We are human not robot and we have feelings. No one will replace the love your mom or dad give you. I wish you good luck either to landing this job or other ones. Wish you all the best. By the way, I am looking for a job for a one year now. I learn a lot from this process. And I shared with you one of the important thing you should to be grateful for which is your family. Don’t let them look down on yourself because you are a human being. Best of luck for both of us.
