The worst heartbreak i ever felt

Hi, i was dating this guy for a year, we got really close really fast, I’ve always been a player and the girl that everyone tries to get with, but as soon as i saw him i fell for him, it was like love at first sight.. just so you know I’m from the middle east so it’s a more strict area than Europe or the u.s. but that didn’t stop me from introducing him to my parents, my dad loved him like his own, and my dad started trusting him and his family unconditionally, i used to spend weeks at his house, literally spend every day with him, he treated me like an actual princess. but i used to get mad over the stupidest things, and i hurt him. until i did something which caused him to break up with me. and of course being the spoiled brat that i am i started acting out, just for the sake of his attention (which he didn’t give me) and the more he ignored me the worse it got, he finally spoke to me after 2 months, then things went downhill, he would ignore me for weeks then suddenly pop back into my life. it hurt like hell but i tolerated that behavior because i knew that any day he would leave the country forever, this went on for 11 months, until he left on my birthday last week, I’m heart broken, and i need to get my life together because I’m graduating next month and i have so much studying to do, i feel like I’m in a black hole of missing him and his family, and the fear of not finding someone else. I’ve been dealing with severe anxiety, insomnia, and early states of depression, I’m mentally exhausted and i even tried therapy but it didn’t work out. I’m just trying to be okay again but it hurts so much. I’m at a point where I’m helpless, i don’t know what to do anymore and I’m just so tired.
