At one time, I didn't let it show and I didn't let it bother me what most people said or wrote to me, let alone how they treated me. I just didn't care and if I did, it was treated like most everything else in my life where I internalized it. Now, I'm at a point though where my body is waking up and I no longer store everything internally. As a result, I'm much more sensitive about everything than ever before.
All my life I have been an extremely sensitive person. In fact, they label my type of people as highly sensitive people. I'm not sure I want that badge or the sensitivity at times because it seems to just make life harder. Trying to find my way through it is like trying to sprint through a thorn patch. It doesn't feel good, nor is it something you desire to do.
