Hi.
Being a determinist I don’t believe in free will, so have no belief in guilt, in any strong sense. I think we all simply do what we do because of our biological and environmental programming. A few people manage to question their programming and break the hold of unhelpful programms.
I do believe in conscience, but even that needs to be educated. My view is that many people spend over-much time agonising over a whole bunch of stuff which they have no real need to worry over. We OCDers even worry about stuff which is pure fiction.
Try not to beat yourself up over anything. I hope your condition improves.
