As-salamu alaykum - Struggling to Stay Firm in Faith While Living Here

As-salamu alaykum. I’m in my mid-twenties and I’ve been trying my best to avoid anything haram. I’ve never dated, never been in a relationship, and I don’t do things like smoking. Still, day by day it feels harder to stay away from what’s not allowed, whether at school or at work. It seems like everyone around me is in relationships or talking to someone, even some Muslim acquaintances who say they’re getting to know someone with the goal of marriage. Sometimes I think I want to find a Muslim sister to marry, but then I get that worrying feeling like maybe I’m stepping into something that could lead to haram, and I wonder if this is the right way to start a family life. Many people around me are less worried about religious matters, and most consider me a religious person - though I know I’m not the best in my deen. That bothers me because I feel like I’m only trying to avoid big sins, not truly strong in worship. I still struggle with these thoughts and urges. I try to pray, fast, and keep dhikr, and I always ask Allah for guidance and help controlling these feelings, but it doesn’t seem to get much easier. Sometimes it just feels lonely and like I need someone to share my life with. Does anyone have advice on handling this? How do you manage these feelings, keep your iman strong, and pursue marriage in a way that stays within Islamic guidelines? JazakAllahu khayr for any tips.
