Yep, you read that right. Writers are solitary creatures by definition. However, don't forget that as a human being, you need a social life too. Your friends and family are (I hope) your biggest cheerleaders, and they want you to succeed at your craft. However, they would like to see you emerge from your keyboard once in a while and enjoy life outside the writer's imagination.
Don't forget to get out now and then. Have dinner with friends. See a movie. Take a walk. Walk Fido (he misses you too). It helps you recharge your batteries, and sometimes even gives you time away from your manuscript to solve a problem in it. I once worked out an internal conflict by vacuuming the house. No, really! If that doesn't get your house squeaky clean, I don't know what will.
Unless you can get your loved ones to vacuum for you when you return to writing.
