Talking to a therapist would be helpful. Ultimately, though, it's up to you to move away from your identity as a fatherless daughter and your sad story of being unloved and unwanted. Your negative thoughts are preventing you from fully embracing life and its infinite possibilities. It's both scary and empowering to know that the person who can help is right there in your mirror!
Since you're feeling stuck, this is a good time to ask: Why am I holding on to this negative story? How does it serve me? While only you can answer these questions, many of us cling to our painful pasts because they're safe and familiar. We know how to live in that sorrow but building a new and happier existence is the uncomfortable unknown. It involves putting ourselves out there in the world: working hard, taking risks, and getting hurt.
You know how to be a fatherless daughter who feels unloved and unworthy. Now it's your chance to create and experience something different. You can start by replacing your negative thoughts with positive ones. The spiritual leader, Eckhart Tolle, says: “Be the silent watcher of your thoughts and behavior. You are beneath the thinker. You are the stillness beneath the mental noise. You are the love and joy beneath the pain.”
Start taking control of your thoughts. Start setting goals and achieving them. Start looking forward and not back. I wish you best!
