I feel lonely too, partly because I am away from my family and old friends, partly because I don't have much of a social life (I stay at home, don't work, don't study), and partly because my husband and I don't share some interests that I am very passionate about. When I lived with my parents and siblings I could talk for hours with one of them about certain topics. If I do that with my husband he will fall asleep or ask me to stop. I also feel trapped because I would like to do certain things, but the demands of the kids, husband, and house don't let me. I would love to read more, paint, study on my own, etc. but there is little time for me to do that. Also, I am more mess/organic oriented and my husband is, in my view, a neat freak. I have to keep the house in perfect order so there is peace between us. And that is a never ending task. I guess I am a free spirit and should have never married, but WTH, I did. I can't say that I am not happy, though, because my husband IS an EXCELLENT father and husband. He is good; in fact he is GREAT! a little controlling, but he tries his best. We have a family together and we are a happy family. I feel guilty for complaining of not having time for my things. I do not regret having my daughters and I love taking care of them, but I regret having lost my life.
Edited to add: Charlotte, I know what you mean about having a lot of energy and not knowing what to do with it! OMG, I struggle with that a lot. I am often overwhelmingly intense. It is the feeling of having ideas and not being able -due to the demands of the present lifestyle- to work on them. How frustrating!
