I can assure you that you're not the only Mum that is finding it hard. It's a lot!
My daughter was full of fun and life but I felt so split. At times I was anxious that I wasn't doing a good enough job (Oh the Mum guilt!). But at other times I felt this niggling feeling to get back to all I was doing before.
I realised I needed more connection with other adults, particularly other women. I wanted to make a difference by helping woman that felt like I did. So I became a life coach and now I get to help other woman enjoy life and motherhood as much as I do now!
