Guilty
I suffer from it.I felt it when I was a kid and then now too.I asked my mother and she had similar things as another people in my family.I was a very skeptic guy,now I´m not.I think we must eat correctly and lead a health life..but this is spiritual for sure too.Today they made us believe that we have evolved out of a belief in spiritual opression.I learned a lot from the jews who accepted the Messiah.A Messiah who didn´t abolish any Law as we learn in christianity,he is the Son,the primogenit of creation..not God..no trinity either.Whe you transgress Torah we can expect bad things to come...it opens channels to the fallen ones when we get involved in pratices contrary to it to

cultism,for example...Idolatry!
Notice that many of our ancestors suffered from anxiety,depression and unwanted thoughts...it runs in the family.As you can read in the commandments.The Creator visits the iniquity of the parents upon their child to the third or fourth generation.Hereditariety. I came to know there are familiar spirits who follow our generations.I know exatcly what you are talking about.You think bad thing about people around you...you feel guilty and you feel like you have to tell some of them you have thought of that about them.It´s an emotional massacre,opression.
You feel like a monster sometimes!
You are not alone! Relax,you are not bad for it.Maybe feeling that guilty is the way we are being showed how much we have fallen.You are recognizing the bad thoughts,our minds can be rebelious.As it was written,We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
