Career change into Programming

I hate my life. I should have done software engineering instead of mechanical engineering. I'm already 5 years into my career making $75k. Is there any chance of moving into programming with a lateral move or do I have to start over? I don't have much to show for though I have programmed as a hobby on and off since high school. I have made some shitty tools and calculators for work and written some firmware.

Then I'll get a manual labor job or kill myself.
