still not feeling the love

Still not feeling the love, after my partner left me 4 weeks ago for another woman I fell out of love with the idea of being pregnant, I've avoided scans and midwife appointments because I am terrified about going through it all alone, friends and family have said that the feeling will pass and once I see my baby I will feel differently, but I'm scared incase I don't, I have 9 weeks left and still not thought of a name or bought a thing, I've totally buried my head in the sand and am finding it hard to deal with
