Any causes or effects of both moodiness and sleeping disorders instead of depression?

Yes. Sx of moodiness and sleeping disorders are very broad. Have yourself checked medically first to see if there're no medical reasons for your sx. In any case, work on a sleep hygiene to deal with sleep issues and you can monitor your mood through a diary/journal to see what contributes to the moodiness (to find out the triggers). Find a mental health professional to guide you through the process.
Mood/sleep. Mood changes can affect sleep patterns which in turn can affect moods.
