I only get that feeling after coming out of a particularly bad depressive episode. It is like "f*ck everybody. I don't care anymore" which is very freeing. But it only lasts a couple days. The kind of person I am, I internalize everything. I feel too much. It is not good for me. I need to learn to distance myself from these feelings. They are not an accurate representation of reality. (I am just repeating things I have read. Trying to soak the info.) But yes, this is our world, our life, the only one we will get.
