What have I become? A walking dead person. How do I fight this?

What have I become? A walking, functioning dead person. Who doesn't know happiness. Doesn't know what she wants.

I have had a rough childhood. I have always wanted a family and to do well in life. I feel dead instead. No ambition, scared to connect.

Some background: I was love-bombed, discarded when things became rough, 10 days before our supposedly planned legal marriage. I was taken back, then physically abused. When I finally called the cops, he said I had framed him. Later, he kept emailing me for more than a year, saying that he wanted to get back with me, only to start a relationship with another girl.

I am sulking. He got everything. I have lost everything today. Everything. I'm so empty-handed, I don't know how to rebuild. I'm trying my best, but I keep ruminating about how I feel like I'm nothing today. I remember all the hurtful things that were said to me and how they have shaken me to my core.

I have changed as a person. Suffering from depression, dissociation, and PTSD. I have been seeing my therapist, but I still lose my mind sometimes. I lost my job, lost my ambitions, left the country where I dreamt of living, and had to return to my home country because I was not able to handle things alone.

I am weak, burned out, without a job, and with no will to face the world outside. How do I fight this?
