I need to vent...

Okay guys so I need to vent to someone my fiancé and I are talking about trying for baby number 2 at the end of this year my son is turning 6 in July I’ve wanted another baby for a long time I mean bad I have dreamed about having another baby tons of times and I am SUPER excited about having another baby & I can’t wait but I have some worries & I would like to know if anyone else is worried about this too. My biggest worry is I hear everyone talking about god is coming back soon I don’t know if you believe in god but I do I’m not a huge Christian I would be a hypocrite if I said I was but anyways I am scared that I’m not gonna have enough time with this baby like I have my son..what if god comes back and I don’t get to see he or she grow up? Or what if I die before then? Then I want be able to know what happens to my babies and that scares me to death! I I was molested when I was younger by a family member he is not around anymore but still I worry about that with my babies if I’m not around to protect them who will? I just wanna know am I the only one that has these worries about bringing another kid into this horrible world?? I want as much time with him or her just like I have had with my son..what do y’all think am I overthinking this??
