Such a striking similarity to my own path. But I was in early 20s-mid 20s, going through some more difficult times and after a lot of research and study of the nervous system and trauma, I came to the conclusion that neurofeedback seems like the magic wand that had the biggest chance to actually produce a transformative effect.

I was experienced with soldering and electronics (mostly board repairs so not design), but not at a professional level. Initially I got an Analog Devices ADC, which they sent for free as I was still registered as a student at the time. I was trying to replicate some existing open source projects, but on an extremely low cost. Ultimately I got stuck in the weeds, and eventually gave up and just bought the ADS1299EEGFE-PDK evaluation board (upon which the original OpenBCI is based iirc). But eventually, again, postponed that, I was in the process of converting the LabView software to C, and to support real-time signal processing. After a short while I moved to the opposite corner of Europe and all those boards are sitting somewhere in my parent's attic. So the question in my mind still remains. Because neurofeedback does sound a bit too good to be true. But evidence is solid as well.

I will definitely give it another go at some point when life gives me more slack/spare time and space.
