As I see it, you have three options.
The first being you could do voice practice, and put everything you have into trying to be successful as a woman. This option will require the most work, and luck, but it will ultimately pay off the most in happiness. If you can secure a job, some friends, and some hobbies, then you'll be in the place you want to be.
However, you could also temporarily live as a male for the sake of employment and social interaction. You may or may not be able to take hormones while doing this - it really depends on if your breast tissue is becoming obvious or not. Some people can go on hormones forever and still be able to pass as male. This route is also a good choice, because it will allow you to re-evaluate if living as a guy is feasible, and if you receive confirmation that you just can't swing the guy life, then when you're sufficiently prepared to live as a woman again, you will appreciate it all the more.
The third option would be to just stop transitioning, go into therapy, and live and function as a male as well as you can for the next while. This will really determine whether transition is right for you in your mind, and you will easily be able to secure a job (relatively speaking), however you may be sacrificing your personal happiness to pursue success in this manner.
If I were you, I'd pick option two. If you don't pass yet, and don't have the voice yet, then you should work on it until you can pass and speak properly - until then, living as male would be the most efficient, especially for your job search.
I know you don't want to "stop then swing back", but that's probably the best option - though, stopping hormones may not be necessary in your case, if you are describing your appearance precisely.
