Hi Nihilanth! Welcome to Wrong Planet. You are among friends here at WP!
It would have helped if you had described the problems that have put you in such a depressed mood. Still, I suggest that you find ways to occupy and distract yourself.
- Exercise. It generates mood boosting endorphins.
- Read funny stories and watch funny shows. That also generates endorphins.
- Eat healthy and enough of it. Not eating enough makes people tired, cranky, and depressed.
- Get enough rest. Not enough rest makes people tired, cranky, and depressed, too.
- Volunteer. There are people worse off than we are who would appreciate some help. This will also boost your mood and help you meet people.
- Take courses, either in person or online. Some of the online courses are free. It will keep you occupied and improve your mind.
- Take up a hobby. This is a good way to meet people.
- Join a club. Another great way to meet people.
- Get involved in community life. Go to town meetings, events held at local libraries, attend or work onstage or back stage at local theaters, attend or play at sports events, fairs, local art shows, etc.
- Get a job, either working for others or become self employed.
As you can see, there are lots of things to do to keep busy. You can probably think of some I missed.
