One of the good things about getting older is that things like this sometimes upset you less than they would when you were younger. Partly because of age and experience but also becoming more zen as life teaches us. Her words are harsh and cruel, but yours are not. She is a friend, not your wife. You don't share a house and children. There are some relationships worth investing in, like a marriage or a career or your business. But friends who are messed up can mess you up. And if you're damaged or vulnerable, not only can you attract bad influences, you're less able to deal with them. You are young, bright, have your future ahead of you. I'm not saying become a hermit or obsessed with being successful/ rich but move on. Learn from the experience and find kinder friends who treat you right. Yes, focus on getting your head right, but also think about the kind of people you want to hang out with. Think of the hours spent trying to make it right with her. What else could you have done with that time? That wouldn't leave you feeling so bad? I hope you feel better soon.
