Want advice on how to survive in a medical college?

Hey I am a 3rdyear medical student and things have not been good lately in my life. I am in a toxic relationship and because of that I have lost my friends. Frankly speaking one of my friends of my group did not like me from the very starting but still we were together just for the sake. She has manipulated my others friends also against me and now I stand here. They sit with me eat with me ....just completely ignoring my existence. They would talk to each other even if I am in the middle the would surpass me in all conversation even if I am speaking something they would look down and ignore . This is already a hard phase in my life because of all the stree the psm subject is giving me I am not able to study because my mental health is just very bad . On top of that my relationship is toxic we are on the verge of a breakup and I know that is necessary. But in this point this friendship drama. Medicos can relate it's already very toxic in here. I am completely lost , lonely and struggling to survive. Please any medicos here help me to survive through this situation and help me focus on my studies. I need seniors guidance to survive through this . 🙏
