Comet is a very caustic cleanser that can take the enamel right off a sink or bathtub. It is probably doing permanent damage to your mouth, esophagus, stomach, and intestines. It is very difficult, sometimes impossible to repair a badly damaged esophagus. Repeated exposure to caustic substances causes cell damage that has been linked to cancer.
Please go see your doctor (or find a doctor) right away, so you can get help in understanding why you are doing this. That's the first step in retaking control of your life. Some people who self-harm have untreated anxiety. Some have a form of OCD. Both are very treatable.
Sometimes it takes getting really sick to appreciate health. Please get help before you do any permanent damage!
Please go see a doctor and get honest. No one here can help you.
I wish you the best. I hope you get the help you need.
