Why I feel the way I feel

56 yrs old I have always been a go getter in my business anything I did. I went through a relationship that left me feeling worthless and made me feel like no positive believe in life. I have been through child abuse and bad marriage that I was married for 25yrs. Now I have been single for 12yrs my feelings are changed from being very ambitious to no ambition. Why do I feel this way I haven’t figured this model out help me see this through.
