At what age did you?

Hello 👋 , I’m noticing some thing I don’t like about me. I’m 21 and I feel like maybe I’m not mature in this area. I don’t have any set what I want to do. Like I’m not stable in my choices and decisions. I can say I want to go to college and if something else pops up I’ll go with that. My mom says I need to put my foot down on something and stop blowing with the wind and I agree because the other day I even had problems with making a decision between what’s best. I got nervous and scared and I asked my mom for advice. Was anyone else like this at my age or do I need help? Give me advice I been worried about this😞😞
