If you want to do it go for it. It'll take a while and there are no guarantees that you will get into med school, but if it your heart is in it, go for it.
People will judge you so don't advertise it.
but there are nurses who have done it and are happy.
It's a longer path, for sure. Being an RN prior to becoming a MD probably will make you are better MD in the end. Just carefully consider all factors involved: length of education, costs, can you deal with both of those burdens, understanding you will be a novice in your career again, I hate to say "age" but can you practice long enough (barring things you cannot foresee) to compensate for retirement, etc....
