Surgical menopause ? any idea?

its been a year after i had my total abdominal hysterectomy with only the left ovary being taken out , i have been feeling quite moody and lots of changes in my body ... like being stressed out so much and so easily , ive never felt that before , i have been experiencing coughs and colds every now and then, is it normal ? i still have my right ovary with me so there's still hormones .... what can i do ?
