Well, same feeling but as they say, learning is fun. However, I have been experimenting something else for the last week(don't wear the pendant anymore) and so far, this little pendant is doing a great job. I will give more info later on if the results are still there.
I stopped wearing the pendant for the last week, and I felt better emotionally. The first day I still had the depression, but I realized that I also had the same focus that I had with pendant. But after some time the depression faded away, and my mind became less focused, but still better than before. So I guess that I can consider this device as some kind of brain training, like neurofeedback. But I must make a plan for using it, because I cannot wear it 24/7. Last night I put it on when I went to bed and I woke up shortly after with some nightmare. I took it off and slept afterwards without nightmares.
I forgot to put on the Qlink after showering a few days ago, and noticed I had fairly vivid dreams that night, some with content that seemed to send a message to my conscious mind, (which I SHOULD have written down, in retrospect) in contrast with the times I had it on. It did have like two weeks with poor sleep before that though, so maybe the observations are confounded and I need further trial and error. Maybe by looking at the fruits of the message of the dreams can help determine whether the influence was a positive or negative one. Furthermore based on this:
Of course, depending on what exactly it does and how it works (if it works physically), then that might mean that if you have wonky EM emissions due to... whatever... then wouldn't it just resonate with that and send it back?
Like: Let's say it's supposed to resonate with some EM field at frequency X, amplify it, and radiate it back into your body.
Normally, that might strengthen you. But what if something is wonky, and your Frequency X is a sawtooth wave instead of a sine wave?
Maybe that might cause it to enhance the bad waveform at a "good" frequency... Causing you to explode or something.
I'm wondering more about how they actually work, and will be experimenting more with it. Maybe keeping it off for sleep? Or only wearing at work? (where I'm surrounded by wifi, radios and repeaters, and massive cell tower nearby). It is possible that instead of a 24/7 wearing application, even in a relatively loud EMF area like where I live, a more specific and nuanced approach is required to use it in a beneficial way.
