I feel so selfish but I'm just sad

This is the only place I can whine and not hurt my husband's feelings or make him feel inadequate. The house we live in is old and needs quite a few repairs. We had a great opportunity to buy another house that's bigger, newer and nicer. My husband and I are both self-employed so we deduct all that we can off our taxes. Guess this has come back to bite us in the butt. I tried to get a pre-approval at the bank and because of our taxes we can't qualify for the house now. We make great money but we're stuck in this crapper because of freaking taxes.
Now the guilt....
With so many people losing their homes and jobs you would think I would be grateful for what I have. I feel quilty for wanting more than I have. All I know to do is pray for what's right and move on. It makes me sad and I feel like a failure for not being able to provide my children their dream house. I will recover and I am very blessed.
