accepting my pregnancy

I'm 25 weeks and this is my 2nd pregnancy. I still cant believe I'm pregnant...like I dont think I'll believe I'm having another baby until I'm actually in labor! I'm scared bc I feel like I dont care. I just do what I want, put all my attention towards my daughter (she just turned 1) & I dont take any prenatals... they were making me sick so I just stopped all together. I should try something else I know.. We haven't even bought a single thing for this baby.. it just doesn't feel real like I'm pregnant and gonna have another baby. It took us a year to have our 1st and this one took us by surprise. My husband doesn't really acknowledge this baby, hes not the same as when I was pregnant with our first. idk I hate the way I'm feeling, is this normal? im just so scared yall... I want to feel happy.. I'm scared I'm going to go into shock when it's time for this baby to come!
