Struggling to focus my thoughts, seeking some support

Asalamu alaykum everyone. I'm a student preparing for a medical career, and Alhamdulillah, I usually manage to balance my studies with my deen. Lately, though, my mind keeps drifting towards someone-another Muslim-and it's becoming a heavy burden. Out of fear of Allah SWT, I've avoided speaking to them, but my thoughts are constantly occupied, Astagfirullah. It feels like a whisper from shaytan, tempting me, and while my prayers have actually become more sincere through this struggle, I'm exhausted by having this person on my mind all the time. I'm young and know marriage isn't my focus right now; there's so much I need to work on myself, 😂. But this mental loop is affecting my daily life and peace. If anyone has faced something similar and has advice on how to redirect my thoughts and find peace, please share. Jazakallah khairun.
