Unsure of myself

How does a person go from living a life a stress and fear, to a peaceful life?

Without spilling my whole story, I (30f) have always struggled with a stressful life. No help from family I have made it on my own. Went through a divorce 3 yrs ago. Ex was an alcoholic. I Never had kids because of past family trauma.

Now I rent a home, new amazing boyfriend and a good job. I’m not stressed about anything. But now I’m jumpy, like something is going to happen, or something from my past is going to pop up again.

Do I just need a hobby or therapy? I don’t have many goals or even know where to start so I can start “thriving” instead of just surviving. I feel I have no purpose.
