guilt feelings

I am an only child with two parents age 83, and 85. I am single, never married, retired and have been there for my parents for over 42 yrs. I recently have had to place them into a nursing home due to their health and lack of money to hire someone to care for them 24/7. I very much wanted to allow them to stay in their home they worked so hard for all their life but, could not do so financially. I now have such strong feelings of remorse, guilt, anxiety and want to move on with my life and enjoy whatever years I have left doing things I've only dreamed of doing, one of which is to travel across the U.S. on my motorcycle and see things I've only dreamed of all my life. I feel in some respects that I have abandoned them. Has anyone ever felt this way before? If so, spiritually or otherwise, how do you deal with these feelings knowing you have been there for them and done for them always?
