Ladies! I'm an emotional wreck!

So I'm 23 weeks pregnant and  my partner and I have just gotten a new puppy. She is only 8 weeks old and our house mate had friends over last night so it was very noisy. It was about 1:00 when we went to bed and they were so rude and loud that it was hard to sleep. We had the puppy in the bathroom just for the night (it's a massive ensuite so she had plenty of room to go from our room to the bathroom and back). To make a long story short, It was around 1:30am and everyone was still very loud and the puppy was crying. I went to go and play with her and just found myself on the floor crying my eyes out because I had this over whelming thought of oh my God what if I can't handle the baby crying when he comes.. if I can't handle a dog crying how the heck am I going to do this. Everything started getting to me and I got so overwhelmed, I put her down and climbed into bed. I sat in bed and just bawled my eyes out. My partner can get to sleep very easy and quickly and noise doesn't bother him which I really envy of him as he could sleep and I couldn't haha. As soon as I started crying he rolls over and starts freaking out, he asks if I'm okay, what happened.. I just looked at him and cried even harder. He knows me very well and knew that I would have just been over thinking things again. He pulled me close and he held me tight and started singing Bob Marley 'don't worry about a thing.. cause every little thing is gonna be alright'. It was the sweetest thing he could have done and the simplest haha love him to death and can't wait for our little man to come!
