You Cannot Control Your Mood

Today, I went for my regular mental health check-up.
There, we talked about how moods are invisible and difficult to control, so it is better to focus on controlling our actions instead.

When my mood goes up, I sometimes end up overdoing things. That stimulation then causes my mood to rise even further.
In my case, because it is a medical condition, those ups and downs are quite large, but it seems that everyone experiences them to a greater or lesser extent.
It is fine when I am in a good mood, but it is quite tough when I crash, so I would prefer to keep my mood stable if possible. Therefore, I have to take measures...

So, returning to the beginning.
While there are many situations where it is realistically difficult, I would like to try to stabilize my mood by controlling my actions.
