<human>: Provide a brief overview of the text.

so yeah, I'm 17, turning 18 in two weeks and I know that's really young but this situation doesn't suck any less just because I'm young. 

I was dating the love of my life for almost 3 years. He broke up with me about 3 weeks ago, and he's ALREADY dating another girl. He told me that he wasn't interested in another, but here they are already saying I love you. 

I am so beyond livid. I've been crying non stop since the break up, I'm more angry now than I was sad. I need some reassurance that my feelings are warranted, because people are making me feel bad for being upset about this.
