Mental Block

Currently, I am trying to let go and I am trying to do what I must. These two things feel like opposite ends of the spectrum, but at the same time maybe doing what I must is to let go. Either way, this does not take away the overwhelm. This does not remove the anxiety because what I am experiencing is normal. Any human being would feel overwhelmed when going through big life changes. I am moving from one country to the next. I am expecting reverse culture shock and new culture shock. A lot of things have been within my realm of expectation, but, boy, was my body not prepared. The physical anxiety, the breathlessness, the constant suffocating feeling, the feeling like I am drowning, and, oh my goodness, the restlessness. How can one be so tired, yet so restless? It's all counter-intuitive.  And yet, here I am.
