My father helped me find a job everywhere, all of them were shopkeepers and factory workers. I feel humiliated when I invite people home for a drink and ask them if they are hiring?

You are too strong. You have no job. Your father is anxious to find you a job. You are still ashamed. There is nothing to be ashamed of. Otherwise, you can find your own job. If you find a job that you think is suitable, you can earn some living expenses first and then change it when you have a good chance.
