I understand that overwhelming feeling of nothingness but guess what the more you dwell on it the more it gets to you.
So let me give you some tips that helps me.
1)Get a new hobby you will be surprised how practicing something new can take your mind off boredom
2) join an NGO or volunteer for something that takes you out of the house.
That way you will meet new people and make new friends who may in turn take you out of your boredom.
Whatever you do, pls dnt let this thought consume you else you will be on your way to depression.
