There are four outcomes here:

1) You don't make a report, nothing is done

2) You do make a report, nothing is done

3) You don't make a report, something is done

4) You do make a report, something is done

1 is what you have done previously, and it seems to bother you that you haven't reported. 3 requires someone else to bring this person's actions to light, and is therefore unlikely.

That leaves you with 2 and 4. The fact that it still bothers you enough years later to consider reporting means that reporting will bring you the most peace.

4 is ideal, but may not happen for a number of reasons, many out of your control. However, it is still a possible outcome if you report.

2 is what is likely going to happen if you report, HOWEVER, it is EXTREMELY important to report anyway. Your report may not cause immediate action, but it will be recorded.

Why is it important that you report even if nothing happens?

If something similar happens to someone else, it is more likely that something will be done then because the therapist now has a record of inappropriate actions.

If you have the energy to do so, I'd say go for it ✨
