Actually there are some symptoms that come with menopause. Depression is one of them. Have a look the mental and behavioral symptoms of depression:
• Moodiness, feeling weepy
• Irritability, lowered tolerance
• Feeling guilty
• Unable to cope, feeling helpless and inadequate
• Problems in relationships, at home and at work
• Sense of blackness, which nothing can penetrate
• Losing a sense of who you are, having a skewed perception of reality
• Can't concentrate or make decisions
• Constantly worried and anxious
• Lose interest in sex
• No motivation, no enjoyment of life
• Thinking about death or contemplating suicide as a way out - if this describes your state of mind, please seek help from your doctor at once.
If you have four or more of these symptoms of depression, you could have slipped into a depressed state without even realizing it.
Fortunately, there are treatments for depression, natural remedies and self-help strategies that can help you feel better.
Wish you all the best.
