Help us w/unexpected expenses

Our baby Tristan was born with a heart defect that required heart surgery at only a week old. This has been the hardest thing we have ever been through but we have faith in god's healing power. All this has taken a toll on us financially (gas going to hospital, meals while at the hospital, and parking). Our AC unit also broke and we have not been able to fix. We got no credit line, we've been denied for loans, and we dont have the funds to replace the unit. We ask for your help. All we want is to be able to bring baby Tristan to a comfortable home (when ready) and get our two other children ready for back to school. Thank you.
