Do you ever feel like you just don’t know who you are?
I’m lost inside my own mind. Every day is like waking up a new person. I feel different, act different, love different. One morning I wake up next to a man I’m deeply in love with and the next I feel nothing towards him and don’t feel a connection at all. 
Some days I just wake up and feel completely nothing... I’m just dead inside. I’m nothing. 
I am just a voice inside my head that never stops. Always thinking and always talking. I feel lonely all the time. Surrounded by many, many people, but still...lonely.
I can never be reliable, or faithful or promising, cause in that exact moment...who am I? 
my anxiety overwhelms me. How will I react? Who will I hurt? What will I regret? What decision will I be happy with the longest? It’s never ending. I’m exhausted. Broken. Lost. Right now. In this moment. Yesterday I loved the life I have. And today? Today I despise it. I want tomorrow.
I live on eggshells. If I try to change things to much, I’ll regret it tomorrow. Or if I don’t change anything I may still be unhappy tomorrow. So tell me...
how do I be happy? How do I know who I’ll be tomorrow? How do I find ME?? How do I make sure I’m not miserable the rest of my life? 
what is wrong with me?
how do I fix me?
I'm lost and I’m scared.
I have a name. But no identity.
