I feel exactly the same way. My ds is giving my dh and I real problems now and consuming our lives. When we are driving, I look at pretty apartment buildings and think how simple and peaceful my life would be if I lived alone. But it would get lonely eventually. I won't leave because of both of my children, but I take as much time as I can get by myself. Otherwise, I would shrivel up and die. If you can get away, do it! Take a vacation by yourself!
