4.Anger and aggressive behavior
Bursts of anger may not always be a result of your personality. In fact, it could be connected to depression, some researchers say. According to them, depression isn’t always just about having a lack of energy or experiencing sadness — you can have aggressive behavior as well.
5.Sleeping too much
This disorder is called hypersomnia and it may stem from things that prove it isn’t just tiredness, doctors say. Some autoimmune diseases may cause the feeling of wanting to fall asleep just about anywhere. Also, having alcoholic beverages before sleeping may cause this effect.
