The middle of the night

i can't stand it i will be sleep pretty decently even though i wake up a few times which is normal for me. Ever once and a while i will wake up once and have a hard time going back to sleep and my mind starts racing normally all thing i really rather not think about of course.I go threw every possible way i could of handled things differently and most of the time end up pissed off or cry in in the middle of the night. It drives me nuts i just want to be able to sleep normally. I guess its because its the only time i can't really distract myself by doing something else. but with the baby coming soon i would like to just have one night to sleep well with out a nightmare or waking up thinking about all these things.
