My girl broke up with me

Hey guys so I’ve been together with my girl for almost 4 months , and I felt like it was going great , after being together for 2 months the problems and fights and arguments kept increasing and we tried our best to work through them but lately they’ve been exhausting for me and her and we said some shitty things , yesterday and today we weren’t in a fight at all and today morning she just called me and told me to check our insta messages where she later told me she wanted to break up to focus on herself more and to focus on her religion and studies cus she didn’t have time to do that when we were together , I honestly don’t know how to feel , this is my second breakup and my first time being broken up with and it doesn’t feel good .

I’ve been sad all day and idk what to do so if anyone has any help or advice on what to do just lmk 😭😭
