Thank you so much, @indieterminacy, @becha, and @how!
I am really glad I shared my thoughts, because your replies are being really helpful for me, especially as this is going to be my first OFFDEM.
Especially after reading the methodology, I can really see that it is not just about getting as much as possible in (something I personally get tricked into very often), but about creating a safe space for real exchanges.
The thing is that I did not want to give up on FOSDEM altogether, but I feel more like I can, now.
See you at OFFDEM, thanks again! 
P.S.: I can’t believe I did not find the anticapitalist affirmations before… They are a true gift for the soul. Thanks so much @becha!
