It's hard to get used to a lifestyle especially if the getting used to is mostly a battle between your mind and your body. Your body is needed to be at a specific place performing the specified tasks but your mind is wanting to do something else wandering out there... wanting to be somewhere, longing for the familiar faces. You are not able to do it, so your mind tells every single vein in your body to enjoy whatever it is that you are doing at that moment but the mind knows better... the mind knows that what it is telling the body is not that easy. The body responses and does what needs to be done accordingly and it feels anxious, nauseous, tense. The mind says, it is okay... you'll get through this one day at a time.
