Hi, I completely understand how you're feeling. I had a baby in August and I love my daughter to pieces but there are times when I look back at before I had her and almost grieve for the life I don't have anymore, I miss going out, staying up late, having a lie in til 11am and doing what I want when I want. Now I have this little person that dictates and controls my life.
I have given up work and feel like I am stuck - my home has become my prison in a way; because of the weather it's difficult to get out. I have joined a few local groups though which breaks my time up and enables me to interact with other adults, are there any parent/mum and baby groups where you are?
I think up to a point it's "normal" a combination of hormones and a huge lifestyle overhaul but if at any point you do feel like you want to hurt her or feel that you haven't/can't bond with her or start to experience thoughts of hurting yourself please get help. It's important to have a good support network around you - are your family nearby? It's tough - especially if you don't have any other friends that are parents.
Don't hesitate to get in touch with me if you need someone to talk to who understands.
