How many companies did you apply for? To get my current job, I applied for about 120 positions, interviewed with four of them. It's a competitive market, which means it's a numbers game. Don't give up after applying to a small handful of companies. Also, if you're near Mexico City, try spending some time at a well-connected coworking space like Centraal. If not, check out workfrom.co for coworking spaces near you and start spending time there and going to events. Jobs come easier through connections than through cold applications. Plus you'll probably find encouragement there too.
