Advice?

So a lot has happened lately and I honestly don’t know how to deal with it. I love my family more than anything, they are everything to me. So some would question why I did what I did. 3 weeks ago I left my parents house without a word said to them. Ill be the first to say that it probably wasn’t the best way to go about it. I left because I felt that at 20 years old I needed to figure my life out, I knew that if I confronted the issue it would just cause more arguing. I didn’t want to be told to stay, I didn’t want to be told that I was making the wrong choices. I felt extremely alone like nobody understood me and I just wanted to figure myself out and what I wanted in life. I didn’t want the pressures of everyone’s opinion on my wellbeing. Sadly, I did not contact my family after I left, they got in touch with me 2 weeks later. I understand that I worried my parents more than anything, I know that I hurt them, and I feel like the worst person in the world because of it. But all I wanted from this was for them to say we understand, I knew they were going to be upset in the begining but silly me believed they would see why I did this. I didn’t do this to be called a coward, a dissapointment, or uncaring, or selfish. I didn’t do this to break anyone’s heart or show that I don’t appreciate my family and what they have given me because my family is my world and I’d never want them thinking that. I did this to make a point, that I’m finally taking my life into my own hands, that I’m done fighting, and that yes I am an adult and its time to be one. I am lost and very confused on who I am and where I belong in the world. I don’t fit in and I can’t seem to keep happiness, it just comes and goes. But I will figure it out and I know things can only get better from here, once you have reached rock bottom you can only go up, right?
