Mixed emotions about rainbow baby..

Hi ladies I found out I was pregnant a week ago I’m 5 weeks and 2 days I’m just having a hard time I’m still just not able to be excited about this pregnancy and I feel bad for feeling this way but since my miscarriage last November I just feel kinda numb towards it this time. I would just really appreciate some words of advice on how to maybe deal with this. Don’t get me wrong I know I’m so blessed to be pregnant an to have another opportunity at being a mom but I’m also scared/anxious my first appointment isn’t for another 2 weeks and I just can’t seem to shake the feeling of what if i miscarry again.
