Busy life of being a single parent

These past couple of weeks have been very draining for me. My son had an asthma attack and as developed pneumonia. I was so scared, I had never seen him that sick before. Now my son has suffered with asthma since he was a baby but he had never had an attack that serious. It was even more so hard because I am a single parent. Now while my children's father is apart of there lives I use the word "apart" very loosenly, meaning that he is not there as he should be. I have great support from my parents and a two best friends but it still very hard raising children alone. I was so well still am very stressed with trying to make up homework and of course making up hours that I miss because I still have to support my family finanically. I realize that I really need a break but I have to keep pushing because failure is not an option. I pray that GOD will see me through this term successfully!!! WOOOO SAHHHHH
