Why is everything so complicated

I just decided to move. I´ve felt I need to for a while now, and yesterday I decided to actually do that. I need to move if I´m ever going to try to do all the things I want to do. I can´t do that if I stay here.
I told my parents about it yesterday. And first they thought I should do it. Thought that it was good that I wanted to move and try, I´ve never wanted that before. Partly because I´m very close to my family, my sister is my best friend, and I don´t want to leave them. And I guess I´m afraid of failing, and it´s so much easier to dream, than to actually do it. And dream, I´m the master of that.

But then yesterday, when I had told them I was planning on moving, I was away for a couple of hours and when I came back they had changed their mind. I have a puppy who´s only about 6 months, and I can´t leave him alone a whole day. And what if I have an hour to work, and I have to leave him at a dog day-care and that cost money, and... I had a little breakdown I guess you can say. I had really made up my mind about moving in the fall or something, so I can work a little and get some money before I move. And then they tell me I can´t just because I have a dog. It felt like I´m not supposed to be something. Like I´m not meant to be someone. Just work a little every now and then, stay here, and just not be someone. Just someone that keeps dreaming and wanting things that will never happen.
When I was going to sleep, I had breakdown again. Just because I really feel like I have to move. I have to try to do the things I want to do. I´m not getting any younger, and I´ve been holding myself back for too long. It´s time to do something.
I`ve wanted a dog ever since we had to put the old one to sleep about 7 years ago. And I love my puppy. But, and I know I´m overracting a little bit, but it felt like he was standing in my way, that I can´t move when I have him. I don´t want to wait 13 years when I probably don´t have him anymore. Move then and try doing things then is just a little way too late. And I don´t want to sell him just so I can move.
My parents said that if I stay here, they can help me when I´m at work and stuff. And I know they will, and I understand how they think. But I just got so upset.

I talked to my mom a few minutes ago. And then she asked me how I felt today. And said that if I want to move, I should do that. i can leave the dog with them if I want to. Try to see if I can get an intership at that magazine, like I wanted. But I´m not going to to that. But if they say it´s okay for me to move, and leave the dog with them if I can´t take him with me. i think I will actually move. And hopefully I will be able to take the dog with me.
