There is no particular reason for Depression. Some of which I have understood after deep reflections are as follows:
The roots of depression:
1. Childhood Trauma
2. Bad Parenting
3. Bullying
4. Death of loved one
5. Emotional Attachment/ Emotional dependency
6. Breakup
7. Always made fun of him/her
8. Suppression to share thoughts due to small age
9. Physical Abuse
10. Sexual Abuse
11. Lack of guidance
12. No Role Model in house
13. Bad Reference point since childhood
14. Suppression of emotions.
