Support Needed for Emergency Travel and Cremation

I'm not one to ever ask for help, but unfortunately, we need help right now desperately. I had already had a trip to England planned, but my husband's sudden death made us have to buy an emergency one-way ticket to England before our original flight, which was supposed to be May 4th, and we were to return the 15th. My beautiful husband just passed, and I'm devastated, barely functioning. We thought we'd just miss our May 4th flight to London and still be able to take our return flight home, but if we miss the flight from Dallas to London on the 4th, it cancels our whole trip. Our only answer is to cancel our flights and rebook the return flight home. The problem is it will cost almost $3000 each to rebook this flight due to how much more it costs now than when we originally booked it. This is the only option now, and after all the extra expenses we've had to pay, we do not have the means financially to do this. Now we are also looking at cremation expenses too for my beautiful husband Lee that I just had to take off life support and watch him die in my arms, who had no plan or money for his death. I am asking our friends for any help they can spare for us in this tragic time. I don't know what else to do at this point; we're desperate and heartbroken. So we are turning to the ones we love to please help any way you can. Even if you can only pray and share this, that will be appreciated too. Thank you all for the support on the worst day of my life.
