Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. I suggest you that confusing about symptoms and mood which occur when we are really happy and really sad, may lead to real mental disorders. Ask yourself. Are these mood swings that extreme? Why they happened? No clue? If no clue (Only if there is no clue even after extreme brain bashing), you can approach a psychiatrist or psychologist for correct diagnosis. Never ever make self diagnosis. It is more dangerous than you think in mind related matters. Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
