Am I crazy because I hate imagining myself like this -->?

I see moms & I even see my own mom and think to myself "I don't want to end up like that". By that I mean, most mothers seem to start neglecting themselves after they have children & honestly that scares me because I'm afraid just having kids & a husband and having a boring job and a normal house & everything ..... just being typical... scares the heck of me because I don't want to be that. I feel awful saying it but I really don't. I mean, I want a husband & some day kids but I'm just afraid I'll get bored with my life or something......
