Answer

The meaning is mostly right, but the traditional phrase is usually written as:

Micchāmi Dukkaḍaṃ or commonly: Michhami Dukkadam

A more respectful version would be:

Michhami Dukkadam to all my friends. If I have hurt you in any way, knowingly or unknowingly, through my thoughts, words, or actions, please forgive me.

Explanation

Your message expresses the right intention of seeking forgiveness. However:

• “Michammi Dukaddam” is not the most common spelling.
• “frens” and “you guys slay” make it very casual.
• For a Jain forgiveness message, it is better to keep the tone humble and respectful.

Spiritual Understanding

Michhami Dukkadam means asking forgiveness for any harm caused knowingly or unknowingly. It reflects humility, non-violence, and purification of the heart.

Takeaway

Your intention is good. If it is for close friends, your version is okay casually, but for a traditional Jain message, use a more respectful wording.
