We were together 4 years and I broke up with him

We honestly had one fight over and over and over again. He’d say I don’t give him enough time etc I told myself if it happened one more time I would end it because honestly I felt guilty whenever I was busy with work or school and couldn’t see him but these aren’t things I can put to the side, and besides school is my number one priority. Last night we had the fight again, he took a bit far by saying he thought I don’t know how to love, but I didn’t fight back just apologized. At some point he asked me if I was done and I said yes I think I am. He begged me to stay, to give it another chance but i said now. He insisted on calling me in the morning and I said okay I’ll listen to what you have to say but it’s not gonna change anything. Today he asked if I was awake, and when I replied he said “it’s all good, I don’t want to talk to you anymore.” It’s officially over, and I know it was the right decision but I can’t help feeling really sad. I just want to sleep all day to avoid thinking. I feel like I’m going insane, and I just need someone to tell me that I will get through this, and that it is temporary, pllleeeaaassseeee
