First, give yourself a two-way hypothesis. If you give up, what should you do next and what will you get? If you insist, what should you do and what will you get? Divide into two boxes, add them in these two boxes respectively, and see which number is bigger in the end, and naturally choose which one.
Second, we should make clear goals and plans and plan carefully. Although your first venture was not very successful, you have accumulated a lot of contacts and resources, which is a particularly valuable asset. Therefore, your goal is detailed, even if you do it every day, you should plan clearly and work towards it. Nothing is impossible as long as you persist.
Third, discuss with your family and listen to their opinions. They are the greatest strength and care behind you. That's all that matters. Because you are not alone, you are responsible for the whole family. If you continue, it will do great harm to your family and make them pay for you. Then you can give up. If your family supports you, then you should stick to it for them. Maybe you will succeed in the future? Maybe you are one step away from success?
Finally, I think, whether you give up or persist, you should not regret it, because life does have many opportunities to turn over, but the choice is always helpless, and there is no right or wrong. It's just that you have to understand that the first thought in your mind at this moment is to continue or give up?
