@toughNectarine1180 sorry to hear about the breakup. Your life is worth more than her. You are more than a bad breakup. Don't let her or her friends see you sad. I don't know if you are religious, but God is the way to true happiness. It's probably not something you want to hear, but I speak from experience, after 14 years of marriage myself, and being abandoned by my ex, left with no where to live, no money, and debt, I once felt like I had no life without him. I once felt like I had no place on earth.
I started going to church,and just letting God deal with me and heal me, I got the strength and courage I put my foot down and divorced that sucker.he never thought I would do it. But I did. I opened my own business of making candles and my kids and I are doing great. I would have never opened my business if I was still with him. I know that's a fact.
And you can find that strong you inside and let it out with power. You are loved. You are important. You are not only someone, you are the one. Find something healthy that makes you happy and do it.
