i have the exact same issue since i got DP and it's often still hard to deal with this. i spent days researching this topic and most of the time i got convinced that free will really doesn't exist and it made me very anxious, hopeless and nearly suicidal. but (and i hope that gives you at least a little hope) now - 1 year later - it doesn't bother me so much anymore. and i think this is because i started to realize that there are really no final answers to this question. it may be that most of the scientists believe that we don't have any control, but there are also other scientist and philosophers out there. in the end i can decide which concept i want to believe and this should be the concept which makes me feel better.
here are a few things which helped me looking at the free will issue from another perspective:
Edwin A. Lock -The Illusion of Determinism: https://www.amazon.d... will is causal
Jeremy Sherman: https://www.psycholo...ree-will-debate
Steve Taylor: https://www.stevenmt...al-of-autonomy/
i have not read this book until now, but i think this might be interesting too: https://www.amazon.d...343AVFRXDD2M6W2
i hope this is helpful somehow!
and I think chip1021 is absolutely right, in the end it's all about stopping the obsession.
The thing is, I can very easily just go on in my life and not think about it and have it not bother me, but then when I remember it it's like "oh yeah, my life has no meaning, I'm not in control, nothing means anytbjng" and that's why I wanna resolve the issue and make peace with it somehow, not just ignore it.
