Hmm on a mission to find my purpose

So I've had my squabbles with trauma, and I've lived my life sort of in isolation. I'm 27 with no kids and no romantic partner. Lately, I've been unhappy and I feel that I'm just existing. I'm a teacher's aide who works in a transitional kindergarten school. I love it, but when I go home, I'm left feeling numb and anxious. I still live at home with my parents and I have finished my bachelor's degree. I feel that I'm waiting for something to happen or I'm overthinking what the next step is. I originally wanted to be a psychologist, but as time passed, I realized I love working with kids, especially little kids. Since I have my bachelor's degree, I've been thinking about getting my teaching credential to hurry up and get a big girl job. I feel like I'm dragging my feet with a lot of things, like dating, pursuing a career, and overall participating in life. I feel like maybe I shouldn't overthink these things and just go for it, and if I regret it, oh well. I'm so antsy to live life that I ironically end up procrastinating or in freeze mode because I don't want to make the wrong decision. I feel like I should just go out there and explore the world until I find something that lights a fire within me. I want to go live life.
