I felt unwell.with tum pains back ache and completely exhausted.THE i work 55 hours in a busy environment however I didn't feel like my upbeat self at all.The GO said it is hard to know what caused my mood dip apart from seasonal affective disorder.Perhaps a virus.Blood test arranged this week.Then I thought I'm 52 could this be the menopause.Would it cause a sudden mood dip?My hair has been greasy Nd I felt just so unlike myself.Any advice gratefully received.
