I don't think Happy Belated Bombaversary has quite the ring I'm looking for so I'll just congratulate you on having made it in one piece and in your right mind. I'll drink to that!!
Listen, don't pressure yourself too much if you can't move to your brother's place. You could actually use the time you have to be near your H for YOU to shine to yourself and prove that you can handle it!! It will pass. Everything does. Remember when you were at school and had a test in your least favorite subject and you dreaded the day of that test? Well, it eventually passed, right? If you have to be near your H you can demonstrate in a mature, not "mean-girl" way that you are sexy, have it together and are not broken.
