Its difficult to conclude any diagnosis from only limited history. Crying is a normal emotional response to any stressful situation, frustration, emotional turmoil, tension, problems. When we are emotionally not well with tears in our eyes, we do feel less energy and motivation to do things.  So , it depends on the presence of other symptoms also to conclude your diagnosis. Perhaps, you can explain in details the chronological appearance of these symptoms, with total duration to answer your concerns.

Low mood , decreased interest in activities, increased thoughts could be because of depression and anxiety. Consult a psychiatrist.
