It is definately normal. How you are feeling now proves that you have experienced DEEP love for this girl.
I know the feeling you are experiencing. And yes, i know it hurts and it feels like the end of the world, but if you believe in fate, then you should know that if you do not end up with this girl...then it wasn't meant to be:/
When your in this state of emotion, your heart feels dead and you feel like you cant go on....but let me tell you that you CAN get through this, you CAN be the person you use to be again, you CAN live and enjoy your life as a young adult....don't let your feelings get in the way of your life, okay? That's the sadest thing to see happen after a serious relationship, I don't want you feeling this way, love.
Theres nothing I can tell you to get you to eat, sleep, and enjoy your life again...this all starts with YOU, but I do want you to know that I, as a complete stranger/friend, do support you and want you to get through this because I've been/still going through all of the things you are going though right now.
I don't know anything about you, except that you love this girl and that you want to be with her like crazy...and that's exactly why I wanna help you...
I hope to see you improve as a person and as a man in the future
Goodluck & Godbless<3
I felt like that too...like things were happening that has never happend to me before and it felt like forever.
But just be strong for yourself...it is very normal
