temperance struggling - Addiction to sweets

Hello.

This is my first post here but I've following the stoicism life for a while (since I had a health problem 2 years ago).

I believe I apply 3 of the virtues, but I do struggle with temperance.

I'm addicted to sweets (anything with sugar), and I can't control myself, I buy chocolates and similar products hidden from everyone daily. I always say that today is the last time I will do it but the next day I will do it again.

Since it is not a "serious" addiction, I can't find any support group and at home, I usually get blamed and shamed which makes me hide even more.

What do you guys do to deal with temperance issues?

Thank you
