Hi hun, I really feel for you! Especially since you have just gotten back together with your OH, its crucial that you spend some time together.

Have you tried a baby sling or something where the baby is still held against you but you can have full use of your arms? I'm not much help coz im expecting my first, but i'm more than happy to lend you a shoulder if you ever need to cry or an ear to talk to. I really hope things get better!
Perhaps talking to a doctor...
