I failed a lot of times running after people that didn't feel the same way for me. I treated them like they were my everything but they just treated me like another someone they knew. I gave up a lot of times and still every time I start loving someone new it never tends to work out...and it tears me up inside realizing that they are starting to fade away from my life and eventually they'll be gone.
You know what ? Yes I have changed. I'm not as nice as I used to be, because I don't want to get used or walked over, I don't trust everyone and tell them my secrets, because behind every fake smile is a backstabbing bitch. I distance myself from people because in the end, they're only going to leave. I have changed because I have realized I'm the ONLY person I can depend on.
