One day I'm up the next I'm down

Well, where's there's good news, there's also bad news. Wednesday was supposed to be a very exciting day with signing contracts and getting one step closer to reuniting our family again. We get a call on Wed.from our buyers saying their bank is no longer funding loans at this time and they will not be able to obtain a loan. They said they immediately got on the phone and started shopping around for a new bank to help them obtain a loan. They had some meeting last night with the bank they chose. Well, it's 1:23 pm the next day and we still haven't heard anything from them and Joe's even called them and left a message. I am numb. I don't know what we are going to do. That was our last chance to get our house sold and move in time for Isabella to go to preschool. I physically, mentally and emotionally can't go on like this anymore but what choice do I have. What can I do? I've done everything in my power to make this work and I failed. I cry every day. My kids see me so unhappy. I can't even remember what it feels like to be truely happy anymore. My world is crashing down around me. I feel exactly like I did when both Joe and I got laid off in the same day; helpless! I'm going to lose everything. We've worked so hard the past 6 years to get where we are. We have perfect credit. I've never paid one bill late in my entire life and here I am thinking about foreclosing on my house. I've given it 7 months and I can't get this house sold. I'm not trying to be greedy. I will live in a shack so that I can reunite my family again. I don't understand what I did to deserve this. I'm a good person. I follow the rules. I don't have nice things, I don't buy anything for myself. I'm not irresponsible. I do the right thing. I've prayed to God so much in the past 7 months. I don't understand why He is letting me down when I need him the most. I know it's not my place to question God and why He leads us down the path we go but I don't get it. For the past 7 months I've done nothing but put my faith in Him that he would get us through this in time and it looks like we lost. We lost the fight. I'm not a selfish person anymore. I only want my kids to have a good life and I can't get them that. I only wanted Isabella to go to school next year; give her a good life. My kids are not being raised right. How healthy can it be for them to see their mother crying every day. I can't even pretend to be happy anymore. I'm just numb. I just get through the day somehow. I'm sick to my stomach right now just thinking about the next step. What are we going to do? No one has the answer. No one. And no one gets it. No one gets that I'm trying to raise two children and this is affecting them. This affects all of us. As awful as it sounds, I think everything would just be easier if I weren't here but that would be the ultimate in giving up. But the world has given up on me so who cares if I give up on the world? It doesn't seen irrational to want my family to be back together again. I got married and had children for a reason, didn't I? It wasn't so that my husband could live in one city and I could raise my children bymyself in another. I'm more depressed than I have ever been in my entire life and there's nothing I can do to make it better. This is out of my hands and beyond my control. And I'm so sick and tired of everone's advice. "Chin up." "Keep your head up." "You are so strong." "You are such a trooper." "I couldn't do it." "Smile." "It will happen soon." "Your house will sell soon." "I would hate for you to lose everthing." "You can't foreclose just so Isabella can go to school." I mean are you serious!?! WHAT ELSE AM I SUPPOSED TO DO?!? Seriously!
