What should I do if I want kids but can't find a husband?

I wouldn’t rely on dating apps to tell me who I was compatible with. You can confront your anxiety/fears yourself if you really want to.  Get involved in things you enjoy, try to be positive and more outgoing, volunteer for a nonprofit you care about, join community events, a sports team, join a gym, exercise. You’ll feel better about yourself, develop confidence and meet people who have similar interests, making it easier to make friends. See where the friendships go, it’s a good way of getting to know the complete person. Don’t rush into anything or settle for less than what you’re looking for.  If you both like each other you can try dating and if that doesn’t work out, there’s still the friendship.  Even if you’re unable to have kids, there’s other options like adoption. 

Visit your local Catholic Services, BUY one like anybody else.
