To put it simply, focus on God and don't stress about the future. If you put God first, God knows what you need and will provide for you. I'd also add that you should pray often. Don't just pray about how you're lonely once and forget it. Pray about that everyday if necessary. Also, when you pray and ask for help, you have to genuinely believe that God has taken care of it for you. You shouldn't pray and then be plagued with doubt that God isn't going to provide (obviously you shouldn't pray for hedonism, but that goes without saying, and wanting a woman in your life is not hedonism).
