The thing about most Abrahamic religions is that indoctrination into your chosen sect often relies on proselytising the vunerable, especially young people or those searching for answers that could potentially ease some of the suffering they experience in life.
Concepts like hell and eternal punishment that are found in Christianity and Islam serve to instill fear and allegiance to God in the hearts of his followers. You have to keep people ensnared in the belief. After all, many people would turn away from theology if there was no allure to the idea of spirituality. For some people, religion brings them comfort, for others, they have been manipulated by fear of the rapture, permanent damnation, the inferno, and feel they have no other choice.
I would not worry about whatever the Bible says about who is going to hell, and who isn't, because no one truly knows. That book has been translated, retranslated, and altered countless times to suit the desires of whatever emporer or King held power at the time. So no one will ever truly know the original scriptures nor their intentions that have been lost to time.
Also, as I mentioned before, these sort of tactics are meant to elicit fear, not put you at ease. When I was very young and was sent to a religious pre-school and kindergarten, it was drilled into our heads what would happen if we didn't accept the word of God- the juxtaposing images of the glitzy streets of heaven versus the eternal torture pit of hell.
As I attended more mandatory church services throughout the early years of my education, we were told even more horrifying things about how God cleansed the earth of all sinners through the flood, but sin was inherent in humanity and we would all need to repent to go to heaven. They even told all the little girls like myself that our anatomy and our role as "mothers and caretakers" was a punishment for the original sin of Eve. Such a loving God to do that to us, huh. That's when I started realizing that there was a malicious side to the church.
Once you realize these things are meant to scare you and aren't for your benefit, it becomes a bit easier to dismiss the threats of divine punishment as inconsequential. I understand how you feel though. It has been years since I was forced to partake in religion, and I still feel anxious about hell sometimes. I cried as a 3 year old over the scriptures in revelations that foretold the rapture, so I am well aware of how much theism can take a toll on your mind.
Hope that you are able to make peace with this and not have to worry so much about the idea of hell. There is no proof that it exists, and even if Christianity held the truths of the world, the bible has been altered so many times, one cannot come to a definite conclusion about certain aspects of it. One would assume a loving creator would not subject people who are hurting and in pain to go to purgatory simply for ending their own life if it were full of suffering.
