I do think I've learnt some emotional regulation skills over the years, as well as learning to appreciate the now with more zest than ever. I've learnt life is precious and it's a waste of time holding onto the life you've already lived. Plus, when I met Jamie I became deliriously in love, and have remained so, so that most longing has faded.
Maybe it's just understanding how mine - the - brain works, and how extricate myself from pointless dwelling on things I can never get back.
