I've had family members who tried migrating (from a 3rd world country to a 1st world one). They are amazing workers with years of experience but they have no post-secondary education and some didn't finish high school. They didn't speak the language.
It was a terrifying experience to see from the outside. I can't imagine it first hand. Physical laborers are so exploited my family had to come back. Housing problems, they weren't getting payed properly, overworked... all this when they at least had the safety of a contract and visa. I was worried they were suicidal.
Unless you get extremely lucky, try working towards some type of certification and work experience and learning the language. If anything, at least focus on becoming mentally stronger so you can endure that type of hardship.
