I can state with almost certainty that your experience is a result of using OGSF. I have experienced similar things with it myself, such as being overwhelmed, strong headaches, nausea, depression, and hellish nightmares. These are all common symptoms for me. I was traumatized as a young kid and these programs bring up years of repressed emotions, were my brain essentially transforms into the mindset of my six-year-old self, leaving me feeling trapped and incapable of escaping it. What I believe is the reason why things are unnecessarily challenging for me, and possibly for you too, is that using OGSF in the US format, following the prescribed settings, creates too much pressure if you are sensitive. I had the same issue with OFv4 as well. In hindsight I think I had been pushing myself more than I could handle for three months straight, resulting in constant depression, nightmares, and other symptoms.
If I were you I would take a break for a while, then I would try to lower the volume or switch to masked format to see if things get easier. I was only planning to try OGSF for one month, and my subscription is almost over, so I won't get to try that out. However, that is what I would have done had I continued with it.
