I'm living with my mother....

My fiancé and I are house hunting and are having a lot of trouble finding something we can both agree on and that we can make feel like home. We just started our search last month and I know these things take time but I am due january 25th and wanted to be in a house by the time baby arrives. We are living with my mother because we didn't want to continue to pay rent at our apartment, so we found someone to sublet and moved out a few weeks ago. I am really struggling because I don't have a space here. We can't set up a nursery because this isn't our house and I don't see a point in doing that. I just feel sad because this is our first baby and I don't get to nest and prep for the baby like I had wanted to. I feel like a loser living at my mothers. Hopefully we can find something sooner rather than later
