I find myself giving up on myself a lot faster these days. Especially on the things that are relevant to me. People and things that I feel a lot for. I just give up. Somehow the early abandon draws little hurt as compared to the blow after a long run. I'm too scared to invest more of my heart and my soul into them. I always want to try but when the time comes and people start to hurt me even the slightest bit, my heart immediately shuts. Closed. Please explain to me why.
