Switching from Breast to formula

Hi All , I have been breastfeeding for 5.5 months and at 6 months I have made the decision to switch straight to formula. I feel absolutely awful about it because of the pressure around me of how frowned upon formula feeding is and by my pushy health visitor. I have loved breastfeeding and grateful I have come this far but my baby won't take a bottle so once I have her onto a bottle I daren't risk going back to the breast as she'll refuse the bottle again. I am exhausted and I am starting to get anxiety , I need some balance in my life and I know now is the time to switch. I was just wondering what to expect from a breastfed baby after they've switched to formula, will she be cranky or will she be ok ? I'm so worried that she won't take to it well and then I will feel awful! Anyone made the switch after 6 m

onths and can offer any advice or give me any reassurance ? x
