I'm scared now!!😖

So I really love my SO, and I really want a family with him. A baby that is from HIM!! So we've been TTC for about a year and 3 months now, after my MC. And idk, like out of nowhere I got this reaalllyyy weird feeling... Thinking things like, what if something goes wrong in my pregnancy? I'm scared of labor & it going wrong 😖 scared of what if me & my SO ever split up and I become a single mom??? I'm scared of becoming a single mom.. What if I can't do it all by myself ?? 😩😩 what if I can't give it the life it deserves?? I'll be a first time mom. I have a job and everything but I'm still feeling like this. Idk why. Just out of nowhere!!  UGH!! I'm very scared & nervous now. 😭 sorry guys but I just had to let this out somewhere.
