I’m so scared

Christian ladies please help, I’m 14 and this has happened before but I started thinking about eternity again and it scared me so much I almost threw up. Its so hard to understand and it’s so so scary.

Update: I guess the thing that scares me most is the fact that there is no end. It just goes on forever and it’s really hard to explain why that scares me so much because I love the Lord and am so grateful for everything He’a done. Maybe I’m so scared of it because I can’t completely understand it. There’s no end, ever.
