Permanent Chastity for Single sissies?

How would single sissies facilitate permanent chastity decisions and have the willpower to do so. I have my psychiatrist (female) have me on SSRIs which make things impossible, but to take it to the next step, what is it? Neosteel masterpiece and throw the key away? Financial Domme is an option, I suppose.

I found a simple solution after my wife dumped me for a real man? after our divorce and things settled down I wrote her a long letter telling her of my love and worship for her and all the sissy cuckold things that I missed when we were married, I sent her the keys for my chastity device and there they stayed for 2 long years, we even met on a semi regular basis after this and she ensured the torment was even worse.
