Best xmas ever

Hi. Im 32 and from The Netherlands. I've got a beautifull wife and we are blessed with 2 children. Since my wife got diagnosed with MS and she had to quit her job, we have been struggling to make ends meet. I love my family and I work hard to get food on the table and pay the bills. We barely make it each month, but that's OK. We are together, have a roof over our heads and we can feed and cloth our children. But we can't do anything extra, so with christmas around the corner I feel like I'm failing my kids and wife because I can't get them any presents. They will go back to school after the holidays and will be confronted by the other kids in their class with their brand new stuff and they will feel left out. I wish I can make this the best xmas ever. I would be ever so gratefull.
