I have more questions than answers, but I hope they help you to reach a decision.
Why do you want to study on the east coast? Is it just that you want to spend some time there seeing the sights, or is it really that you want to go to school there? Perhaps you just want to get away from the family? How do you intend to pay for school? Out of state schools usually cost more. Are there good schools on the west coast? How often will you be able to travel back home? Have you been away from home before? These are all things that you need to think about. In the age of social media, one is never far from home anymore, but, there is still no replacement for a physical hug. Try to think through what you want to do and WHY you want to do it. You can always get in an east coast vacation at some point. Going to college may not be the best way to do it!
best of luck!
I felt the same way at one point in my life when trying to decide to stay close to home or move to the east coast for school. Consider several points to take into account in order to make your decision. Write down what schools you want to attend or have been accepted to, both west and east coast, decide which school best fits your interests and major- if you know already what you are planning to study, consider yours and your family's financial state on what you can afford. How supportive is your family about your dreams to be on the east coast? In this modern age you can reassure them that you can stay in touch with them in a million ways as if you're still there. Write out all the pros and cons to help best make your decision. Hope this helps.
