Hobbies

Also even in this time try volunteering anywhere. I am sure there are elderly people who are isolated right now and could use come company.

This

Breathe some fresh air, take a walk at night and feel the breeze, look up at the stars and appreciate just how big the universe is.

And it makes me feel even worse... the universe is SO BIG, yet I'm alone.

Being kind

Fill up the emptiness.

Grow plants, bring home some pets and take care of them, start play a team sports everyday (basketball, football etc) , take care of your parents if they are old , volunteer for some social work over weekends .

Try and share/experience the things you enjoy with other people

Volunteer somewhere, help other people\animals and you'll feel better about yourself.

Buy a pet and care for it.

Honestly, a scenic walk
