Certainly not and considering the almost non-existent side effects, it is at least worth a try since it looks very promising. You are right that it is a tiny study but it doesn't mean that it has no value.

I have to say that I know people like you very well, I almost can hear the "go see a therapist and take your meds" or better "don't try and certainly don't think you can solve this on your own". A positive force first and foremost acknowledge people's potential and doesn't put roadblocks everywhere.
