Daniel,
Prof Bouloux is not a specialist in PFS, he is a fraud that pretends to acknowledge its existence but feels it is linked to mental health issues. He pays lip service on visits to the office then writes to your GP indicating it is mental health linked, he has done to you as he did to me, and as I hear he has done to many others. Don't give the fraud another penny.
I know it can be hard to take stuff in with brain fog, I found it exactly the same, but I sat a weekend aside, went through the information CD from this board had laid out (which was on a much less helpful forum than this so it took some time to sift through the bullshit from other members) and just made notes, I got what I needed in place and started a few weeks later and never looked back. I was also coming off all kinds of medication at the time, and that made things extra difficult to deal with, but once you get through the first few weeks things get better QUICKLY. You really wont believe it. And the good news is the mental stuff is the typically the first thing to improve, from my experience and the others that I have spoken to that commit to the plan.
Stop trying to treat symptoms and work on treating the cause holistically. Its not easy but you realise very quickly how worth it it is, particular if you are very bad off. Get on http://www.totalmaleoptimization.com and get things rolling.
