Super overwhelmed...

So I had to recently move back into a small apartment because my boyfriend and I broke up and left our giant house. We are currently working on things and everything is going great. I just unloaded and situated all the stuff from my shower yesterday and I'm just feeling super overwhelmed. I am in such a small space. I'm going to be going from his place to my moms place to my place and I just feel super super overwhelmed. Maybe it's the thought of a newborn coming? I'm not unprepared in any way shape or form and I know this baby girl will have everything. Maybe it's the small space or the going everywhere to be with everyone. I do not know. Any tips or opinions on how to calm down and feel comfortable?  This is the current space I have in my room for her. I can make it work and only have a few months until I can get into a bigger place. But still just freaking out over how much space I do not have.
