I think the topic i have choosen is the booming one. The person who likes to remain lonely, keep on thinking, not having any kind of interest or no interaction with the world around, we can say that the person is under depression. This is my personal expericen thats why i can say this.

May reasons can be there which may cause depression:

1. Lonelyness

2. Health

3. Money

4. week in studies

5. Unemployeement

6. mental tourcher about personal weekness

7. Failure in each and every attempt etc. etc.
