Feeling ungrateful and upset

It's hard to feel thankful and grateful when you feel like crap! I am upset we can't have another biological child because I could pass the lyme on. I am upset that I feel like crap and it's hard to make it though the day sometimes. I am upset I am dizzy, and feel like I have a hangover many days when I didn't get to have any fun to cause the crappiness, I am upset I have become a homebody just to survive, I am upset that I have to bring my own food anywhere I go because I can't eat anything that is normal, I am upset we are majorly in debt because of all these stupid medical bills, I am upset that I cause major stress in my marriage and to my family, I am upset that on weekends all I want to do is cuddle up in my bed and sleep the time away, and most of all I am upset that I could have unknowingly passed lyme onto my 3 yr old daughter. She is getting tested in 2 days. Am I thankful for how far I have come, yes, but not today! I am just UPSET and ANGRY with life!
