I've always found that 'spiritual but not religious' is a decent way to answer questions like these, with the best success of avoiding detailed explanations and additional questions.
Maybe there is an established religion out there that is compatible with your beliefs. But I think only you can determine for yourself, if and when you come across it - because, just as much as it is about core ideas that match, 'feeling right' about identifying with it is equally important.
Others' perceptions of you may depend on the overall dynamics of where you live. I've certainly met many people with unconventional belief systems, and actually - these are some of the most interesting people to converse with. I love discussing (but not debating!) spiritual concepts - one really can learn so much.
Good luck with everything.
