The best way to bash yourself is by listing things that are true. This shouldn’t be difficult if you’re honest.
If you’re that lazy, you can also use things that are not quite true, but can’t really be proven false.
If you’re stuck in writer’s block, buy a mirror and refer to it often for inspiration.
In the event that you have friends, ask them to be honest about you.
If you find yourself exceptionally easy to ridicule, try not to get too carried away. People might start feeling sorry for you.
Think of something you would like to be good at, and come to the realization that you’re painfully awful at it.
Pretending to be a loser can sometimes make it easier for you to accept the fact that it’s true.
Stay away from generic phrases like “I’m a loser” or “I’m a failure.” People will just ignore you. (Not like that’s anything new)
It’s not necessary to say “I have problems.” If you’re making fun of yourself, it’s obvious you’ve got problems.
