Help with Medical, trying to live

I have suffered from chronic pain for over 20 years. Last year I had knee surgery and missed 3 weeks of pay. Never really caught up. This year I had a second surgery on the same knee and a month prior had neck surgery back in February. I have had nothing but problems since. I can't get a full weeks work in yet. I had stage 2 hypertension after surgery which resolved itself which was many visits to doctors and cardiologist and ER. One night stay for observation of possible heart attack. Now I have a lot of fluid build up in my neck, you can see in my pic and severe fatigue. I wake up exhausted and do my best to get as many hours in at work as I can. I am barely making my bills and the only reason I am is because I sell items on my free time. I have many more doctor visits and bloodworm left to do to figure out what is going wrong. My orthopedic surgeon says it has nothing to do with the neck surgery. I am desperate for a doctor to find out what is wrong. I pray for a miracle daily. I have even told my doctor I feel like I am dieing slowly and was told to come back in a week or two later for blood work. I also need to see my psychiatrist due to the extra stress this has put me through but can't afford the $300 visits. I am begging anyone to help. This is so hard for me to do but I just gave my landlord half the rent and every other bill, electric etc is about to be turned off. Being homeless or trying to move when you take all your energy just to get dressed in the morning seems impossible. Plus I don't have the funds for a truck to move or deposits. Please if you can even donate $1 and enough people do then I can slowly pay some things off. The doctors tell me not to stress but the longer I'm ill the more stress I have. Please more than anything, add me to your prayers. I know with God I will get better. Thank you in advance for any donation or any prayer. God bless!
