K.P.
The night after my father moved M. into a tiny apartment in the middle of Poughkeepsie, NY for my residency... I sat on my second hand leather sectional and sobbed. My parents and sisters were a plane ride away, my aunts and uncles 4 hours away, my grandparents about 30 minutes away. I knew one person and had met only the people who interviewed M. at work. I was wearing a huge diamond and was pretty sure I didn't want to marry the guy I had moved to NY to marry.
Then it hit M.... this was "it". I was starting my real life. I was an adult. I was on my own. I made my own choices. I was terrified because if I failed, it was 100% on M.. I was excited because if I succeeded, it was also 100% on M.. I had to figure it out on my own. My parents couldn't do it for M., nor could they fix anything anymore. I couldn't pretend that I had it all together when I didn't.
You are going to be great. It's not going to be easy, but you are going to create this life for you and for your daughter. You will make mistakes, but you will learn from them. You will have months when you are eating rice and beans, but you will get through those months. You will have months when you call off a wedding and second-guess yourself, but in the end you will know that they are YOUR choices and YOU can live with the consequences.
Enjoy this time!
