Think about the damage you will do to your body. Purging is not worth it. You may feel empty but you can achieve the same feeling if you wait a bit - instead of purging drink some tea and/or go for a walk. That will help you much more.
If you don’t purge now, it might be a lot easier to not purge the next time, when you have the urge.
Also even if you say that you are ugly - in your opinion, mind you - please keep in mind that purging will NOT make you beautiful. Your face will be swollen and over the time the consequences of purging will affect your appearance/your body and health.

If anyone else can think of any reasons please reply to this message - not into my ask but directly to this because I won’t be on here anymore today/this night.
