BLACK CLOUD!!!!

Will someone please tell me how to get rid of this big black cloud that is hanging over-head!!!
This week has been a rough one, mom has had her 2nd. chemo treatment and her hair is falling out now and I feel helpless to the situation and have no clue what to do.
I spent Sat. at cheerleading comp. in RI. The girls did great but did not place. Jessie looked like a little mother hen, she was so cute trring to take care of the girls that were crying, I was so proud of her. Tracey and I went to DC. last tuesday and we had a great time. She said that the interview with the FBI went really well so we shall see what happenes. Going back to sat.(sorry I keep bouncing around, but I haven't witten in so long) when we got back from cheerleading Mike got called into work and Jess went out with some friends so I had time alone at home with the dogs(Cooper and Sadie(moms dog)) I was doing things around the house when Sadie had to go out, well she saw a rabbit (the one that lives in my garden) and she desided to chase it. Sadie is such a strong dog and when she went after it she almost knocked me down and the leash sliped out of my hand, I kept calling her but she would not come It was so dark outside When she crossed the street and then I crossed the street, I was still calling her when she ran right in front of a car and got hit. She was hit hard and when I got to her and brought her to the side of the road she died while we tried to get help. I can't even tell you how awfull I have been feeling I had just talked to Mike and we were going to keep her if mom could'nt and cooper really liked having her around (he cried sat. night dogs are so smart they know when somethings up) needless to say it was awfull having to tell mom she was ok and more worried about me only because if dad was here I know that I have let him down and I always hated it if I disapointed him(mom said that he would not be disapointed because he would know that it was an accident) It was just a awful night.
Lets hope that things start to get alittle better. Sorry that I am such a downer. When I say that I need a night out with the girls youall know that I mean it!!! And I promise that I will not be a downer that night!!!!
Thanks for listening.
