Maybe the Paraliminals have helped unlocking lots of hidden emotions, hurts, etc. In a way you are "emotionally detoxing". When people undergo detoxing, there is an initial stage of release of toxins which makes them feel rather unwell for quite some time. I think you should be thankful that the Paraliminals had an effect on you. Of course, you need to persist and be patient so that your temporary downturn can pass and you can go back and surpass how you were before you started using the Paraliminals.
