Desperate for help!!

I have been picking my skin for as long as I can remember, but started picking the inside of my ears about 4 years ago. They will scab, leak, smell, and eventually get infected. The only way I’ve been able to treat the urge to itch has been getting prescribed antibiotics from a doctor after having a severe infection. This will usually cure my ears for a few weeks, until I find the urge to pick again and the process starts all over. It has gotten so bad that I almost always have a constant ringing in my ears. I am running out of hope, if anyone has any suggestions or has experienced the same thing I would love to hear what has helped you!
