It is time to accept that life is going to take you through a thousand different situations and emotions to get you exactly where you need to be. You are going to have to accept that change is coming, and that change is OK.
When something new comes your way, you need to understand that embracing it with all that you have will only make the change better. If you are holding back from the change you are going to miss out on some of the best times of your life. Embracing something new is terrifying, but it is also beautiful. All of the changes that you are undergoing have been exactly what you needed at the time that you needed it. When you needed to meet a new person, you started a new friendship, even if it was not with exactly who you thought it would be with. When you needed to get away from a relationship, something happened to end that relationship, even if you didn't understand it at the time it was exactly what you needed.
Stop thinking that you know that everything is better if it stays exactly how it is. Change is a natural part of life, everything changes and that is how it is meant to be. You have changed, and there is nothing wrong with that. You aren't the same person that you were a year ago or even a month ago. You are growing and changing every day. When it comes down to it, you should be proud of everything that you have had to overcome to get to where you are today and you should be excited for all the things that are going to keep changing to get where you are going.
When you think about how terrifying change is, remember that you have gotten through every change you have undergone. Don't worry about what could go wrong when there are so many things that could go right. If you are focused on what is going wrong constantly, you are never going to embrace all of the positive things that are happening right in front of you. Change your outlook on change, it will make your life so much better.
When was the last time you let life happen? Stop hiding from change and allow things to happen for you. You are getting ready to undergo a world of difference, it is going to be beautiful, as long as you let it be.
