A fellow Muslim brother here. How do you manage feelings of loneliness when you've been single for a while?

Assalamu alaikum, brothers and sisters. I'm a Muslim brother who sometimes struggles with loneliness, especially when it comes to being single and never having been in a relationship. I've expressed interest in marriage a few times before, but it hasn't worked out yet. Staying committed to my deen, I avoid Zina and anything haram, but I sometimes have doubts-wondering if I'm enough or if someone will ever choose me for marriage. These negative thoughts can be tough, especially when I see so much discouraging content online. Sometimes I question if there's something wrong with me. How do you, my Muslim brothers, cope with these kinds of feelings and thoughts? Jazakallah khair for your advice.
