It's sad to hear a person who is so lovely and kind, get torn into pieces because of a guy. Do you know how much I feel like punching that persons face for making you upset? I get into an over protective mod. Would you like some friendship love and ice cream? :3 That's what you really need right now. And I will give you a word of advice for the future for your own good (yes, I'm sorry, I'll become a mother right now): Being a relationship in a young age and having your heart broken is not necessary because you have a free life to live until you are 18 and after that, you get thrown under a bus from all the work that's going to be in your hands. Don't let that that guy stop you from being outside with the real world where everyone is here to support you and make you happy, because that's seriously not what I recommend you to do while time flies by. You need to be strong and continue normally. That's the only way to recover quickly, rather than sitting alone and thinking about what a miserable time he gave you, no. But I am going to leave you to do what makes you comfortable. <3
If you need anything, remember we and I am here. For now, take care and focus well on your studies!
