not so good morning

I have had to deal with the baby all by myself for just about 24 hours and I'm pretty damn exhausted and frustrated now. She has been up for an hour and a half. I'm a person that can function on little sleep but this is bordering on ridiculous for me. Sometimes I feel I am in so over my head. I never really wanted children strictly for the fact that I can be slightly selfish and impatient and to deal with kids especially babies you need to be the exact opposite. I don't regret doing this at all my brother and niece need me. All the same I feel like I want to curl up and cry. And yet I feel guilty because whatever I feel my s-i-l felt a thousand times worse.
