I am soon moving to georgia for my higher studies

I am moving to Georgia soon for my higher studies. I was so happy after I got the admission letter from there but as the days get closer to my departure it feels weird. This was my dream to move out from my parents and try to live on my own. Being an elder child i have always been restricted from going out , meeting frds and all.. basically I didn’t have any freedom i have always did what my parents wants never i got a chance to express because even if i try to explain them it will get rejected so it was kind of waste for me to explain them. I started planning to leave this country but now as the days are coming near, I feel weird. My heart sinks idk why but it feels like I won't be able to do it, or it won't turn out the way I wished for. Whatever it is, one thing is for sure, I was so happy before but now leaving my parents and going is kinda hurting me. I hope this feeling eventually fades bec i have a long way ahead.
