Yes I have felt this way. I think all human beings long for the things that are described as a sense of home. I would say that you are not only normal for wanting/missing this sense of home. But normal people who grow up in a "normal" home with a "normal" loving family, etc...have days where they are sad and homesick.

One thing I am currently working on is trying to not to assume that when I am struggling it is because I had a challenging childhood. For me I need to stop thinking I'm the only one who has these feelings.
