First of all, I understand how you feel. But I think since you are so upset, it means that on the one hand, you feel pain, but on the other hand, you feel that you can't give up this internship opportunity easily, right?

Since you can't give up easily, I think it is necessary to analyze the reasons why no teacher is willing to take you. For example, if it is because they spend too much energy to bring you what you need, it is human nature. Then why don't they want to bring it, but the teacher who takes you is willing? Is it because he likes you personally? Because it was arranged from above? Or is someone else particularly good and responsible?

If it is arranged above, you can communicate with it, talk about your current situation and express your need for someone to take care of you. In this way, if conditions permit, I will generally coordinate and communicate with other teachers and try to find someone to take you.

If your teacher is congenial to you or that teacher is very good, then you have to work hard on your own. After all, no one has to help you. It is human to help you, but it is my duty not to help you. If you want someone to take care of you, you should try to behave better, or please those teachers and make them think that you are a teachable talent. I'm a little tired now, but you may be able to help them later. Why don't they like it?
