It is okay to be hurt. It's a good thing. If we weren't hurt by anything, we wouldn't know what mattered to us. :)
It makes those moments when the hurt is vacant all the more valuable.
With regards to me, I see it as a massive positive. I've thrown myself at the gym, and when I was getting dressed for an interview today, I had a shirt that used to fit.. fit as though it was a hospital gown that was too large.
By the same token, I had the opposite problem with my pants. I couldn't get them over my thighs, let alone my waist! So there's positives that have come about due to my retrenchment.
Ultimately, it has allowed me to assess what is important and to cherish what, (and those) that I have. I've been doing a lot of growing (emotionally) and (shrinking - in some places - physically) - while obtaining wisdom, and dare I say it, I'm the happiest I've ever been.
It is a strange feeling, but I am going to enjoy it while it sticks around.
My view is always one of stoicism and nihilism - if I have no expectations of anything, I can never be disappointed. Maybe that's also Buddhist to some extent?
