My wife and I are trying! But no luck...

My wife and I have been living in my 2005 Chevy Tahoe close now to about 8 months and things are going downhill mentally and spiritually. Our relationship has been on trial as well. We both have low income jobs and work our butts off every day, but still barely making ends meet. Our SUV is breaking down one expensive part at a time and repairs are costly and unaffordable. We are living in Texas for now, but need to get back to Indiana so she can see her grandmother before she passes. She is almost 90 years old and is not in good health. Her grandfather has already passed 2 years ago and it has taken a toll on her mental health. Her biological father was never in the picture and her mother didn't have time for her. So her grandparents took on the responsibility with loving and caring arms and raised her. They are all the family she has ever known and the thought of never being able to get back to Indiana to see her grandmother again is tearing her apart. She has been in a deep depression for the last few months and it takes everything just to get her up to go to work. It's breaking my heart to see her like this. I've never done anything like this before and normally wouldn't ask for money, but I dont no what else to do or haven't a clue where to turn. It's our dream before we pass on this earth to be able to make one last trip back home again in Indiana, and then travel the U.S.A. to see national parks and beautiful country sides. To appreciate the nature this Mother Earth still has before us as humans destroy it. If we were to receive anything at all it would be very much appreciated and valued. We would utilize it to get back on track and pay whatever forward we can for the rest of our years to come. We always try to give to people that are less fortunate than us, even when we struggle ourselves. Because we know what it feels like to be "down on our luck". The goal in life is to be kind to one another. Life is way too short to be sad and angry. Thank you and God bless.
