How do I stop my fear of hell and other related fears? I am new to figuring all this out...so help would be appreciated

Okay so for context to assist anyone who wants to give advice to me, I am religious (catholic) but I also believe in science, the reason I believe in both in simple terms is the math don’t math for me. Yes we know the big bang theory happened, but the theory is it started from a singularity kind of like what you would find in the center of a black hole, no one knows what happens if you go through it. So out of this point and singularity, there sprung an explosion that created the universe and in that universe out of all odds a planet was created (the only one we know of right now, though I think it’s highly likely there are other life forms out there) that just so happened to have to develop the exact right conditions for life to develop. And how did that life even develop, primordial soup, the earth’s bodies of waters just so happened to get the exact chemical compounds in the exact amount needed to create organic compounds such as amino acids. So my point in this science brief is that everything we experience and exist in is a statistical anomaly, to many anomalies to make sense for me. Maybe the way I understand religion ends up being correct or not, I hopefully won’t know for a really really really long while, I go with what makes sense to me, but I do know that there has to be some sort of higher power that I don’t understand that in my opinion must be at work within the universe. Despite all I know about science and all I know about religion (my own and others) I cannot shake my existential dread, I can’t shake the awful fear of death. I can’t even enjoy basic milestones in life like birthdays or weddings for people because it always creeps in. It even doesn’t help if I try to think about the concept of heaven and just radically accept that as my answer for what happens after, because then I feel so much fear and dread of seeing the people who traumatized me when I get there. My adopted mom once asked me when I would stop being scared of my abuser ever finding me or interacting me and I told her when the woman is dead, now that’s not even true. I can’t even feel of safety in religion because then I become terrified I’ll be in eternity with that woman, and I’m not even going to start on my religious OCD themes right now. It’s affecting my OCD horribly and I’ve had multiple panic attacks at this point and so so many compulsions, it’s like they never end. For those with death anxiety, what are things you’ve tried that I could try to help? Are there any specific therapies for death anxiety that I could try? I want to be able to take control of my life and be able to enjoy things without always having this creep up in the back of my mind, so I’ll gladly hear any suggestions or things others have tried that could help. Thank you!
