The question to you is, you know you've failed at something, but what are you doing differently this time around? Are you still too hurt to move on? Don't deny the hurt you feel. Go through the storm. Feel the pain. Let out the scream if you must. Hit a boxing bag. Pretend that it's you and hit hard. Let yourself know you've made a mistake. Let it out. Do it as many times as you need until you break. Only you will know when it happens.
Then and only then will you come out wiser...maybe even stronger, and your next step will be a much better one. If you continue to dwell in the past...well, you are just allowing yourself to lose time...and we all know that time waits for no one. He's not our friend. In fact I think he's probably our worst enemy.
You asked, which one am I? Well, it's not who you should be, it's who do you want to be? Society will label you. The force of that label is strong and will feel like that's who you are but it's not. You are who you feel you are inside. That's the only thing that matters.
