I'm so worried

I should be happy that I'm going to college soon, but I'm not. First of all, I'm worried about my mom, since the rest of the family aren't that close to her and things are difficult and I'll be across the country. Secondly, I'm a reserved creature of habit, making this a bit crazy for me. Third, I'm really worried about money and have a lot of anxiety about it. And last, I have no idea if this is the right choice and there's no way to know.
