This is a good sign. Rituals also have the effect of purifying your soul, because they bring your soul to the high vibration.
The cleansing process, as a symptom, can lead to small “backlashes” as in this case. In the cleansing stage, negative energy is released and then eliminated, bringing the soul to a new level.
This is a normal cleansing process, in some cases, you may face, even mood swings, memories resurfacing, trauma re-emerging, blockages, fears and more. This is because in the phase of “cleansing” from negative energies, one has to eliminate by dealing with all that.
Once the phase is over, you reach a higher vibration, are more centered, balanced and connected. Try to create short routine for yourself, in difficult cases, so you don't lose progress by skipping meditations.
