Muslim and Sikh Relationship advice?

I've been going through a difficult time I'm a muslim girl and my boyfriend is a sikh. I know this is wrong religiously and my family would never tolerate it. I fear they would be so disappointed they would disown me. I love my boyfriend and I know I should break up with him but the thought of not being with him gives me anxiety. I'm currently studying medicine and whenever i think about breaking up with i struggle to focus on my studies.

On the other side of this story my friend tried to set me up with a muslim guy who is perfect, he is everything i could ask for and is interested in me. I know i should leave my boyfriend as we can never be together, my family mean too much to me for me to lose them.

How do i go about ending things and coping with this throughout uni? Do you think ending things is the right thing to do? Any advice would be greatly appreciated.
