I'm turning 26

I'm turning 26...I'm married...I went to school and I have a job but I don't make great money. We don't own a home and I've been beating myself up about it. I don't know if I'm being too hard on myself... We live in an expensive area and are sharing a large home with my parents. Many people I've talked to say it's normal to share a living space with parents especially with children (we have two). I mean if we didn't have children I'd definitely being living elsewhere. Does anyone else feel like like this? Or do anyone of you share a home with extended family?
