Just a state of mind?

What makes me feel so down lately? Last night for the fifteen minutes or so that I was waiting for my mom to pick me up, I sat on the concrete stump in front of the guard's gate and cried. At the moment, I was thinking, "why are you crying?" There had got to be a reason. And I knew clearly what those reasons were at that time. It was because one, some very close friends whom, despite knowing them for under a year's time, have become so close to me, are leaving soon. Second, I felt the beginning of the end for me. Somehow, I felt this dreaded enclosing feeling. Just how I had felt when I first came back to Taiwan four years ago. However, a friend once said to me, "Picker, dont stop meeting interesting people, because you yourself are an interesting person." This gives me hope that I wont be the lonely, depressed person I was before because I had compromised with my surrounding. I will continue to be that interesting person, and not let my mindset now refuse what I potentially can be in the near future. Its just a change on how you think. Learn the lesson and get the fuck out of there. I think Ive learnt my lesson from four years ago, and I am now just starting to dig it up because I had forgotten how precious it was. History will not repeat itself this time.
