I doubt you're seventeen years old if you just said this.
Well I clearly did just say that but your doubting my age is probably due to a misinterpretation of my post.
Life is and always will be a competition between you and the people around you, especially when considering "love" It's even apparent in the simplest of animals. So if she left you for somebody else you lost and they won, it's not a hard concept.
you're so loving stupid i can't even express it.
Assuming you're referring to the later part of my message, it's sarcasm.
Would you have preferred that she stayed with you even though she loved somebody else more?
Also nobody is obligated to go easy on you in this lovely competition because you have social anxiety.
