The first routine Chrispe. Feeling like I'm not cut out for this!
You are doing a great job! When the sleep deprivation hits and our hormones are changing, most of us feel like we can't do it. Even those who have had kids before!

Be gentle on yourself. Rest often. Both you and baby have been through a lot. Don't be afraid to ask for help from those who can support you. (family, friends) even if it just getting someone to come wash the dishes or clean the bathroom, or have a cup with you while you feed.

After my first I had my sister (who worked with babies) come stay for a month.
Hugs LN it does get better/easier.
