Absolutely totally fine NOT to visit the newborn. Far too soon for that! And you shouldn't need to explain yourself. I met my first newborn only 2 weeks after my first mc and it was the hardest thing I had to do. I wasn't strong enough and it sent me into a spiral. It took 4 months to feel relatively ok around a baby again. And even now, 10 months on, it creates an uncomfortable feeling in my stomach being around them.
Perhaps see your GP about your feelings. See if you can refer yourself for the counselling, as it will take time and may be worth getting the ball rolling now. Or call the miscarriage association. They were really so helpful when I found myself at my wits end one day. I posted on here a lot, but sometimes I needed to vent and make noise and hear someone hear me. If you know what I mean. And for that matter, I needed someone who understood to hear me. And the lady on the end of the phone did understand. And it was such a relief.
Can you go for a walk, get out the house to clear your head and get away from the whispers? I know it must be so hard being around that when u need to be alone. I'm sure they all care very much, but it is such a confusing time to be on the outside and they don't know what to do. Would it help if you could ask your family to give you privacy? Say you need to be alone for the time being? Tell them you will be in touch when you are ready?
I didn't go away, I only had time off work. And I pottered about the house, and kept myself to myself. I didn't really see anyone other than DH. I drank a lot of wine! And ate nice food. And cried. It was all I could manage! I did spectacularly lose my temper with the neighbours and unleashed all my anger on them one day, shouting and screaming at them for playing music too loudly. Came back in and sobbed and sobbed and felt a lot better!! Not sure they understood, but it helped me!!
I hope you can find some peace soon, but it's totally understandable to be feeling so awful at the moment. I am thinking of you x
