How about doing mold design?

I am a college graduate, 19 years old this year, graduated, specialized in molds, and worked as a mold design assistant in a foreign-funded enterprise; in the previous internship, I worked in a private enterprise for almost a year as a fitter, various machining milling machine grinders cnc, edm, wire cutting, I did it all over again, and finally became a mold engineering assistant. Later, because the engineer who took me had a disagreeable personality, I quit my job and left. After that, I ran to study design and paid me two months of salary. It’s a fast food for 8 yuan. I learned it for nearly 3 months. There is basically no problem with parting. It takes a longer time to make simple products, but I still don’t have enough experience. Later, I can’t make it anymore. I don’t have any money, and the teacher at the training institution ran away and didn’t want to teach anymore, so I was so passive at the time. I paid the money, but the teacher was not there. The day passed day by day. Where did the training institution take care of you and charge you? When I got money, I just ignored it. Basically, I didn't have a teacher in the first month or so. Now I work as an assistant here. The salary is very low. It requires at least 1,000 for one month of food and water and electricity. Then I have a general worker’s salary of 2,000. Here, you don’t need to work as a fitter. You are responsible for watching. The structure is fine, but since I came here, I feel that I have to stay for at least a year or so, so I have no idea, and I want to switch to other sales.

What are you doing? I am not afraid of hardship, and I want to stick to it. However, when I was in my training organization, I found that I was facing a lot of computers, my scalp was numb, and my hair fell a bit, not a lot, but it was really obvious on the pillow when I was sleeping. It’s strange that I don’t have to do it now and there is no problem, so I don’t know how to do it.

Now I’m bored and have been learning English. I still have the basics. I like to be a project engineer, but the qualifications are good, I need a bachelor’s degree, and I need English level 6. So I’m still a bit confused.

Dear like-minded friends, give me some suggestions, thank you.
