Packing to leave your relationship..

We were together for almost 9 years, we have a 7yr old and I am 14 weeks pregnant. I found out he cheated on me while pregnant.. Honestly I'm broken and this sucks. I am leaving to my parents house and I'm having such a hard time packing.. Can anyone give me any advice..? I'm over the tears at this point.. It just sucks to have to leave my home because of something he did.. I also have no boxes so I'm just packing things in any container, bag, or hamper I find.. Ugh it's so hard to pack up my home....
