I do find it alarming that your therapist told you to do that and then didn't want to follow up when you reported negative consequences.

My personal opinion is that religion can be empowering or diminishing depending on the motives of the organization. When I was young, I was forced to join a church I didn't want to attend. In this church they try to convince you that you are weak and helpless and that the devil and temptation are waiting around every corner. The church said we can't rely on our own intelligence but we had to listen the church instead. I know that this kind of church isn't run by a god, but it was run by men who wanted to scare peoole so they would pay money to the church every month to get blessings and reserve their place in heaven. This is an earthly business, not a representative of god.

If the church you go to is sincere, they should try to reassure you that you have the ability to control your own destiny and that everyone was born with equal potential. As an adult, I believe that if there is a god out there, he isn't someone so petty that he will obsessed over whether you followed every little rule or ritual outlined by men who claim to represent god. If there a god worth knowing, he would respect the fact that you are doing your best and that your intentions are good.

It's possible that you would have found a parking space regardless of whether you prayed. Praying is ok if it makes you feel good, it is like a sort of meditation. Praying should not cause fear or compulsion. I'm surprised your therapist won't discuss this with you. But keep in mind that I'm not a therapist and I don't know the rules they have to follow.

This is just my opinion. I'm pretty sure you won't go to hell. You don't seem like a bad person at all. It's not a sin to struggle in life.
