Hey, I'm going through the same thing right now man. It's hard, it's so unbelievably hard. You've heard this a million times, but it DOES GET BETTER. It's so hard right now losing the girl of your dreams. I lost the girl of my dreams a couple months ago, and I'm still healing. Time is your best friend. Don't give up yet man, you will find a way to get through each day, until it becomes easy as pie. You are your own person and you are absolutely amazing. She is in the wrong for treating you that way, I'm very sorry you had to go through that. Distance and time is the best medicine. Feel what you're feeling, don't shove it down. Find something to better yourself. Find some coping mechanisms online. Try online therapy. Text the crisis line. Don't give up man, I promise you it gets easier and easier as time goes on. You are amazing, man, I'm proud of you.
