Michelle, you really do have a lot of emotional things going on in your life. Hang in there!
As much as I don't look forward to the kids growing up and leaving, I know I will have things to do that I enjoy. I have maintained myself as an individual even if I feel that wife and mother define me. I will always be a wife and mother but there is also more to me and there are the things about me that led me to want to be wife and mother.
I enjoy reading, writing, gaming, pretending to garden and other past times. These are fun things now and later I will have more time for them. My husband and I share some hobbies and interests so those are things we do together now and can perhaps do more of later.
Find you, Michelle and get to know your husband as the man you are married to. You might find the search is very exciting and fun.
