How do I stop feeling like I'm alone?

My name is Mesha Peterkin and I never send a e-mail before so please be patient with me. I'm 38 and I feel so alone and that nobody loves me I'm engaged to this wonderful guy and we were going to get married this coming weekend but I lost my job I broke my leg/ankle on March 13, 2010 and I feel so not important right now I feel like God don't here me. If I'm wrong please forgive me but I was raised in the church I don't know whats going on in my life right now I started back to school and I haven't been in school for over 20yrs. How do I stop feeling so down on myself. I play lotto to win money because it's only one person working in the house and I'm use to pulling my weight to help and I feel like I'm useless I know the pressure gets to him sometimes and he is the first guy I ever stayed with in my life I had my first child and only one at the age of 28. I dont mean to take up your time I just feel like I'm alone while I'm typing this to you I feel like crying. I thank you for reading my e-mail and hope that you respond because I need to know why I feel like this. I'm scared that I'm going crazy May God bless you for all you do for people
