I was raised Catholic, I am not anymore but I understand the fears and what you are feeling. I think if you still have your faith, you have to believe that God is still loving and still wants the best for His children. Have faith that He will not abandon you for your suffering, but will greet you with open arms to a better place. The idea of Hell still terrifies me, and though I don't place my trust in any higher power, there are days I wish I could.
