Coping with the quiet after choosing solitude for the sake of Allah

Assalamu alaikum. I've recently turned a new page in my life-I ended some relationships that were filling my days, all for the sake of Allah SWT. Now, I find myself alone again. I miss those people, the laughter, the memories... my heart aches, and I feel this emptiness, like I don't have that one close, beloved person anymore. And I'm still young. I know, insha'Allah, I'll be grateful for this decision in a few months. But right now, how do I get through this? It's as if life has paused. There's no one to lean on, no one to share my stories and deepest thoughts with. I don't attach to people easily, but when someone is special, I truly value them. Now I'm feeling how different life is without them. Also, I plan to remain solitary in terms of relationships with the opposite gender until marriage, insha'Allah. How can I stay patient during this waiting period and manage the pain? It's tough seeing others around me having friends from the opposite gender or even dating, enjoying their time, while I can't. It gets even harder when you don't have many friends of the same gender either, due to not finding like-minded people. I try to have sabr, but waves of sadness hit me out of nowhere, sometimes stopping me from studying or focusing on my tasks. I would really appreciate any advice, especially from those who are in a similar situation-avoiding relationships with the opposite gender, even friendships. Jazakum Allahu khayran.
