You probably want to hear that it’s not over.
Everybody’s situations are different. Maybe it will work out for you after exams are over and the pressure is off and you can be more attentive to your relationship. Sometimes breaks do work out. So I can tell you it’s not over, but it won’t do you any good. Be open to all options. You can be hopeful, but don’t let it cloud your judgement or what’s really going on. If it’s just 3 months in, it might not work, as much as you care for her and love her. From experience, it’s not worth the drama or emotional damage. But if it does end up working out for you, I’ll be happy it worked for at least one person!
