I know a little how you feel about regrets. I regret not finishing university and came to realize lately I would love to be a doctor/psychologist. At the same it doesn't do any good to have regrets about the past. I also believe that we're exactly where we're supposed to be, even if we're suffering - our journey is planned out for a reason. It's better to have this light bulb moment even if you're in the winter of your life....better than never having it at all.
