Nervousness

This week on Friday im getting married. Im so excited which is making me nervous lol i guess it feels surreal because I’m 18 and my life is really about to begin ( we are moving to Korea in July) new home , a baby in November , and marriage I guess since we are going through the court and not having a real ceremony I’m scared It’s not going to feel “traditional” please give me some advice on this new life and what to expect because I’m really nervous
