Swaddling may help. It is so tough in the beginning. I could have written the same exact post when my lo was the same age. Birth through six weeks I though we were conjoined. This in time will pass. Make sure you are drinking plenty of water and have some snacks and a good book ready. Like norasmommy said, your lo is probably going through a growth spurt too.
Hang in there mamma and keep up the good work!!
