I think that it's great that you have come from a healthy, happy home. Your family has done a good job at supporting you and showing you love. That's terrific!
However, you will be entering a different phase of your life. Independent, yes. But there are a lot of benefits to independence. You decide what to eat, when and where you'll eat it. You can look at magazine pictures, friends home and apartments, ad's and come up with plans on how you'd like your place to look. You can do it yourself; have friends over and share supper or lunch for their help; or have family over for their help and have a family meal. Just a few ideas off the top of my head. And, let me tell you,
everyone has decorating ideas! You go with the one/s that you like best.
Loneliness comes and goes throughout life ~ whether I'm with someone or not. I can be at a party and still feel alone. The loneliness seems to come with my general level of happiness in life. My family hasn't ever filled that void within me, so I don't know if you would have that problem or not.
Try not to put too many expectations of yourself and your future. That increases pressure and anxiety level, in my experience. You are young, and have much to learn about and enjoy. Give yourself time to get to know who you are and what you like before trying to fill a feared void in your world. Trust me on this one.

Best wishes!
