1959 - I empathise with your ‘doubts’, which from your post I perceive is couched in a form of depressive reaction. BEWARE, that when in such a mental/emotional state that it is easy to get ‘baby’ mixed up with the ‘bath water’, and that Satan and his mates will be hovering about trying to prompt you away from God and the Church founded by Jesus.
Yes, life can be tough, and people can be ‘unfairly’ judgmental. Humanity is fallible, often wrongly biased and presumptive as a result. Don’t turn other folks shortcomings into ‘shortcomings’ of Mother Church, and don’t make what are really their problems into your own.
Forgiveness is most definitely not an option, according to the life and teachings of Jesus - it is a core part of ‘love’ - but sadly many people do fall short of the target - pray for them.
You are in my prayers.
