It's best not to change companies. You can calm down, read more books to find inspiration, or search other people's papers online to see their ideas, but you can't copy others', try to write it yourself, don't rush for success, ensure quality, and don't put too much pressure on yourself.

Usually it's because you don't have an idea, or your current idea is very poor, so you need to find some ideas. You need to look for information, find some theoretical requirements about your paper, and then continue to write.
