Scientific research is a process to restructure your mind with scientific thinking. The findings in the master and PhD levels are mostly insignificant. You are in the trainning to create new knowledges, not intuitively but scientifically. Common process. Many times to give up. Scientific research should not be difficult. Difficulties are not the aim of research. The entire process of the game is to ceate new knowledge. You should tune yourself at a difficult level, which you can sustain. Most importantly, build up trust with your supervisor. If your supervisor don't know how to do research, you will have nightmare to understand what is research.
