Getting progressively more tired of programming

Some background

28, have an IT degree and created my own (game centric) software company where I had some fun doing management and some coding for 3 years. However, personal and financial issues with partners led to me go job hunting last year. I travelled around Europe looking for jobs (haven't had much luck in my own country even after one year of more or less actively looking). Spent 3 months at one company, 6 months at another and I'm doing remote work now.

I've found that each time I start a new job I get less and less motivated from the onset. I am perfectly aware I'm technically not settling for less every time I jump ship (more pay, projects closer to what I would prefer working on), but there's a huge wave of cynicism that constantly washes over me and I find it harder and harder to do my job. I never found hard programming questions interesting and hated programming contests. I was always more of an engineer, I always enjoyed carefully placing parts in optimal ways rather than complex mathematical calculations and optimizing something to run in .8 seconds rather than .85 for purely academical reasons. I'm the type of guy that thinks making things feel fast is better than actually making them run faster (I hope you understand that this doesn't mean I'll put "spinners" on a modal window rather than fix a bunch of O( n^n ) loops).

The problem

Nowadays, my mind is constantly wondering and I'm constantly trying to force myself to get things done to no avail. I've tried everything: rest, coffee, taking walks, short breaks, long breaks, working abroad, moving back with my partner. Nothing seems to work. I sort of enjoy programming and the occasional new challenge interests me (mostly from the integration and UX perspective) but it's like my passion for coding is nearly completely dead now. In my last few jobs I kept noticing I was the only person enjoying long meetings and I gladly took up tasks like writing documentation or even kitchen work that would give me some reprieve from the torture that programming was turning out to be.

Honestly, it's driving me nuts. I've applied for internships for things more along the lines of production, management or software design but I constantly get turned down for lack of experience. My parents say I shouldn't expect to get "promoted into management" before putting in a few years at a company but constantly seeing younger people with less experience get the jobs I'm aiming for isn't helping.

I'm mostly wondering if someone's been in a similar situation or has some insight on what course of action I should take. My deteriorating mental health isn't making me any wiser.

TLDR: Programming is literally making me feel miserable, please help.
