I depend on my family and relatives for everything. They won't give me a job, and I dare not find a job myself, just like a loser.

Why rely on your family everywhere? No one can control you for life. Learn to be independent. What you are doing now is the result of everything your family has been doing for you, and you lack the ability to be independent. Be confident and bold. Find an easy job first, such as a waiter in a restaurant or a takeaway, and then you won't be afraid. You'd better learn a trade by yourself, so that you can easily find a job.
