It sounds to me as though you have moved forward in your thinking, but at the same time, you haven't found a way to move forward in your living. You should put yourself out there, challenge yourself to meet new people who might be more on your wavelength, people who may not belong in your current circle of friends. Go out and find a hobby or project or activity that will allow you to do something that has meaning to you. If you feel that you aren't physically able to do something with meaning yet, take a class, or course and learn how.
Sometimes when we upgrade our minds, our current circles seem to be on a lower level. This doesn't mean you have to cut them off, but it does mean that you need to find new things to feel stimulated.
