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.

I don't know what that means. It's only been 5 years (3 years at current role) and I am already losing it my cubicle. I'm to take a leave of absence every 5 years? No one will hire me.

I don't know if I can. I have like ADHD or something. I'm having a hard time focusing on my work. I design gear motors for stupid trinkets that really shouldn't exist. I've always liked programming. I know some of the stuff that bothers me (paperwork, idiot superiors that change requirements arbitrarily, etc.) will still exist, but programming seems to be more satisfying when you come up with a solution. When I come up with a mechanical design that works, I feel nothing.

I've only found a couple programming gigs more on the engineering/science side of things. I just applied but looks like I'm shit out of luck because the rest are across the country and I can't move.

I'll give it a shot.
