IUI- TOMORROW!!!

Well, I peed on the stick at 6:30 this morning and go my LH surge!!!  Off to the clinic for us that means for tomorrow morning!  Maybe I will get the best belated birthday present ever (my birthday was Saturday).  This month on Clomid has been the worst yet, but with added stress from DH's family hasn't helped the situation one bit.   We had family reunion this weekend at my SIL's house up north.  As much as I was looking forward to most of it- I was not looking forward to seeing my husband's brother and his preggo wife (yes, this is the same one who I have been having problems with since January or February when they announced they were preggo).  Long story short- I apparently just don't exist to them anymore.  They refuse to look at me, talk to me, or simply acknowledge my existance anymore.  What they did do this weekend was completely ruin my 29th birthday by treating me so terribly.  I never knew that a simple "good morning" or hello back would be so hard for them to give me.  Apparently my thinking that I would even get a "happy birthday" from either of them on Saturday was way out of line.  When the entire familly sang to me- they sat there and wouldn't even look at me, let alone open their mouths to participate-  I spent a good portion of the day on my own outside in a rocking chair crying.  DH is going to call his brother today and share his disappoint with him for the way that they are treating me.  Really, I don't expect to be best friends with either of them- nor do I want to because of the way they are as people- but I do expect to be treated like a human being- that's all.  At one point yesterday my BIL accidently backed into me and stepped on my foot- I said "oops- careful there"- he walked away without even apologizing.  My DH and I have tried to stay true to our Christian faith with this whole situation, but I don't even know what to do at this point.  We have tried to make ammends- our apology was not sincere we were told- I have tried to break the ice by talking to my BIL- he walks away without so much as a glance at me- We have given them hugs goodbye (we hugged them as they stood there) and have been accused of doing things just to annoy them.  I'm done!  Yesterday when we were leaving to come home we got hugs from everyone else in the family (like 20 people) and they just sat there.  I was at the end of my rope and almost in tears again, therefore, they got no hug goodbye, not even a glance.  My DH's cousin talked with them Saturday morning and told them that this needs to stop- she also talked to me and said that I need to focus on the fact that everyone else in the family loves me and that I can't give my SIL the power to make me feel so insecure and upset because that is her entire goal- which I know. The tears have finally stopped this morning, and I am praying that DH's conversation with his brother goes well today, but if not- I am done being treated like crap.    I have a big day tomorrow and need to relax and pray that our 1st time is the charm for us and our IUI. I need lots of prayers for a calm heart and for God's miracle this month.
