I think many of us have felt the same way. The truth is, every older boat presents challenges. Some are worth the effort, others not. Find someone who can help you answer this question first. If the hull and deck are sound, no structural issues, go to work. As the process moves forward, you'll develop a sense of pride and confidence that will make her yours. There are many Cat 27s out there so you can find help, parts, ideas. I'm in year three of my rebuild and have wanted to sink her more times than I can tell you but then I'll have that moment of joy and pride and all is forgiven.
