Emotionally drained and asking for prayer

I`ve been debating whether or not I should even write this post today. As you all know, I am a very open and honest person. I consider everything I write about on my blog as as part of a testimony of how God is working in our lives. The events that have transpired over the last 24 hours are unbelievable.
I want to thank all of you for your prayers for us concerning the new house.The last part of the inspection was supposed to be today and we were actually shooting for the closing to be tomorrow.Within the past 24 hours all of our plans have been stomped on and the relationship with my sister and I has been dissolved per her wishes.Now that I summed up the situation I`ll go into further detail.
My husband has a very serious injury that has kept him from working for almost a year now. He is in so much pain, all the time that he can`t even stand up for long periods of time. When we have to go out, he is usually in pain for several days after. Through this trial, we got into a very bad position with our mortgage. I could not get a job, because I needed to be home to care for our children. My sister is executor of a trust that was set up by my mother. After praying and seeking the Lord, I had decided to ask her for help.She had told me not to worry,and what we would do is borrow money from our children's college trust fund to purchase another home. This house would go up for sale and we could start fresh with a home that would be a good investment for the children.When the time came for college,the trust would have to be reimbursed. After a year of living in the home,we would begin making monthly payments to reimburse the trust plus any interest they would of made. This was wonderful! She had agreed to buy us some new furniture,and help us with some other normal things in order to move.I had called her,to let her know about something that needed to be taker care of before we moved and she just flipped out.She said she wasn`t taking care of this particular thing after we already made arrangements based on the fact that she said she would.Her and I got into an argument and I yelled at her and hung up on her twice which I am not proud of doing, but I was just so upset and hurt. So then, yesterday I got an e-mail from her saying that all deals were off and she wanted all ties with us broken,she`s getting all her contact info changed,ect.There is also another trust that my mom had set up for me, that I was supposed to get at a later time.I got a second e-mail saying that she`s giving that to me now so all ties can be officially broken until I need to speak with her about the kids college education.
So,that`s basically the story in a nutshell. I`m so upset and hurt over all of this. I have been praying throughout this whole situation that God would direct us on the right path and this is an answer to prayer. I`m just really sorry things had to end this way. I love my sister and I always will. I`m not angry with her for what she has done, I feel sorry for her. She`s going to miss out on alot and one day when the kids are all grown she`s going to realize that she was wrong and it`s going to be too late. This is what God wants for us. Now, we will stay here,get caught up,be able to make the necessary repairs with this house and we plan on investing some of the money into a two year CD and when it matures we will start sell this home and look for something Else at that point. Anyway, it probably wasn`t a good idea to make a deal like that with my sister. I love her,as I said before, but would we really have been happy living in a home that she could sell out from under us every time we had a disagreement?
Sorry this is so long. Thanks to all of you that have read through this. I really appreciate all of your support and prayers throughout all this. Please continue to pray that there will be an opportunity for reconciliation between my sister and I, and that God will continue to direct us. Also pray that God will bring peace and healing to my heart. Blessings:)
