Nights are a particularly difficult time for me, weekends less so if I can find ways to be busy, busy, busy. One thing I found helpful is finding a friend who will let you vent your frustrations without trying to "fix it." I also find if I physically work on myself, at home work out (until I start at the gym) and calling different friends keeps me distracted from ruminating.
