Feeling depressed

I'm over looking at names, I'm over caring which gender my baby will be, I'm done with all of the special stuff in pregnancy. I don't want any parties. I kinda just feel like it is what is and he/she will come when they want to come. I'm only 19 weeks and I think everyone (family) has overwhelmed my husband and I to this point. Like I literally don't care anymore. I'm staying healthy for the baby and taking care of myself because I love this baby but everything else can just go away :(
