I've been denied the opportunity to work for a company based off my gender...

As a female in mechanics, I'm wondering if I should make shit easy for myself to have better opportunities by switching careers. That job would have helped substantially even though to them it was entry-level. I mean, now it's a matter of survival and there's no way to keep going on in this male-dominated field if I can't afford living expenses and just get denied repeatedly for career opportunities...based on my gender and not my skills.
