what to do??

Today was a wake up call for me, I gotta learn to walk away walk away for good. Its not a choice anymore its destiny. I can't continue to feel this way anymore to effect my life. I can't be weak anymore to be this insecure. What is happening to me has it gotten worse? Why am I holding on so much why can't I let go?? I need to take the last 6 months to heal myself to make myself stronger, please let today be the new beginning for me. Please let me stop being so weak..I need to think positive, my mind can drive me crazy making me think crazy things and I am face with this challenge and questions keep playing in my mind.
