What does it REALLY feel like to full-time?

We are new to full-timing and are still adjusting. We lived in the same house for 30 years, raised our kids and now have grand kids. My husband is older than I am, he's 68 and I'm 53 so we had to decide whether we should wait until I retired or do something now. We decided it would be now. Put our house on the market and thought we would think about what we would do next. Our house sold in 2 days for full price so the craziness began and we started moving, throwing stuff out, giving things away and getting rid of a lifetime of "stuff" in 30 days. We now have a 36' Winnebago and a small storage area for things we saved for our next home (not on wheels). We bought a used RV (it's in fabulous condition and the diesel motor has 23K miles, almost like new) so we could test out this lifestyle without spending a fortune. We love it so far. We've spent 3 weeks in New Hampshire, Maine and Vermont and it is so beautiful in the fall. My biggest problem is family. I am one of 7 children in a large, close family. My parents are still living and are in their 90s, my older sister just lost her husband who dropped dead one day of a massive heart attack, no warning, no health issues (that was one of the reasons we didn't wait to do this, tomorrow is never guaranteed) and we have 3 new grandchildren. I am so torn between loving this life and traveling with my husband and staying close to home and helping my parents and spending time with our grand kids. Is this a problem for anyone else and if so, how do you deal with it? Our family is very supportive. The problem is all mine and I feel guilty and I feel like I am abandoning my family and I'm making myself crazy.
