Regarding your current situation, my advice to you is that you should first adjust your living conditions, because if your current situation is very poor, it will be difficult to find a job. After all, it's hard for others to be interested in you when they see you disheveled and unhappy. Secondly, don't stay up all night in internet cafes, which is bad for your health and will affect your morale. You should seriously find a place to eat and sleep at present. Finally, don't do things on impulse, because things come step by step. If you really want to set up a stall, you must first understand all the processes and channels. It's no use running like this all day. I suggest you find a similar job before, stick to it and try other projects.
I once had a friend who went through your state. I was trying to persuade him. Later, he almost went through the above process before he regained his spirit, but there were many twists and turns. I hope you don't need so many twists and turns, you can handle your state wisely, cheer up and work hard.
