I would not be surprised since you are regularly and constantly (at least twice a week) reminded that:
- you are mortal because of Adam and Eve;
- you have to suffer all life, missing your goals and making mistakes being imperfect, because of Adam and Eve;
- you are under daily attack by Satan and demons, perfect spiritual creatures more powerful than you;
- you have to be ready to be persecuted to death if needed as a martyr;
- you have to be ready to die avoiding a blood transfusion;
- you have to prepare an emergency bag, keeping it updated and being ready to escape;
- you have to ring door bells of angry people who could even attack you physically;
- you have to control your words because if you express a personal idea in contrast with the religion you risk a judicial committee, disfellowshipping, and shunning;
- you have to be ready to go through a great tribulation never experienced before;
- after one thousand years of paradise still in imperfect conditions, you have to pass a final test where the number of rebels (who could be your family members, relatives, friends you made in the meanwhile, etc.) will be as the sand of the sea...
Do I forget anything?
Anxiety, anxiety, anxiety... Which leads to depression, depression, depression...
