Assalamualaikum - Feeling So Lonely Before Nikah

Assalamualaikum brothers, I’m a college student, never been married, and I try to avoid unnecessary interaction with non-mahrams. I stay away from music and haram content as much as I can, pray the five daily prayers, do my adhkar, and try to keep up with basic Islamic practices and more. Alhamdulillah I try hard to protect myself. Still, the loneliness is really heavy. My mind drifts all day to thoughts of my future wife (if Allah wills). I imagine holding her hand, coming home to her, building a life on the Shariah, spending time together, praying together - all of it. Because of that I sometimes open Instagram or YouTube and watch couples or reels of Muslim couples. One click and I end up scrolling for hours, feeling more empty and my heart aching. I make dua and sometimes wake up for tahajjud begging Allah for patience, strength, and to divert my thoughts, but the same fantasies come back the next day like my mind is on repeat. It’s starting to affect my daily routine and studies - I don’t feel like doing much or focusing on academics. How did you brothers manage this while staying away from haram? What practical steps, duas, routines, or changes in mindset actually helped you before nikah? Any advice on coping day-to-day so I can be productive and patient would mean a lot. JazakAllah khair.
