Familiar Frightening Feeling

I am scared, I'm probably just over reacting again, But I can’t help but think; It’s happening again, I can feel it, I'm losing you again. That ever familiar frightening feeling is back, It is a dark, twisting and churning feeling within me, It is tearing me up inside. On the outside I appear fine to my friends, But on the inside I a mess of emotions, I try to talk to you and fall apart. please dont go again i dont think my heart can take it this time i love you i need you what do i do? im lost help me once again come back to me my dear bring back you smiles and laughter and jokes and joy and your love...
