All I do is worry about the afterlife, will I go to Hell?

Everything I see reminds me of it, I don't know why. I'm a devout Christian but I worry about going to Hell so much. I never saw Hell as a place of torture. more jut nothingness away from God but you hear a lot of more extreme religious people talking about Hellfire so I dunno. I can't enjoy life becaue I think that in 70 or 80 years time I'll be burning for eternity. Don't try to convince me God doen't exist, I beleive He does and you won't change that. But what if the Muslims are right, then Allah will send me to Hell, or if the Catholics are right I'll go to Hell. I'm a Protestant btw. And what if I piss God off and he sends me to Hell, what if Hell is fire and brimstone and I and my family(who are atheist) are there forever. It shites me up proper badly. I hope I won't go to Hell, I am a Christian and suppoedly saved but what if I'm not? The idea that I'll be in Hell forever is driving me insane. I don't really believe it's a place of torture, just away from God, a nothingness, but still, I don't want to go there, and in Islam Hell is definetly a horrible place and what if I go there? I'm so worried
