Emotion, emotional, emotionaly low

Why do I feel low and unmotivated? Is it really work related? I know maybe work triggered my negative emotion. I am considering if the academic work is for me as it can get really boring especially when I have no idea what to think and write. when I am trying to put my thoughts into words, it changes all the time. I could not follow what my thoughts and continue what I plan to write about ...it is getting really boring. what is the point of doing research? My answer would be able to theorize some behaviourial patterns, some good experiences and some other aspect of life people share. why do i want to do research about young children's metacognition? Because that's what learners need in order to improve their performances in problem solving. when a foreign language learner is given a reading task, he is likely to use the most familiar strategies he knows in decode the written language, comprehend the text and make some sense out of what printed. How much he knows about himself being a language learner, how much he knows about the text and how well he can use the linguistic knowledge in decoding and comprehending the tasks are the concerns of metacognition.
