I'm sure you'll be able to figure it out! My best friend was in a very similar boat as you last year, had all the symptoms but their GP referred them to a crappy assessor who took the word of their parents over their own symptoms. They were told they "probably just have anxiety". They were able to find an NP who diagnosed them, and now sees a psychiatrist regularly for med updates.
This was in the USA, which has the absolute most broken medical system in the world, so if they could figure it out I'm positive you can too :)
It seems like the Imgur album only has a photo of the back of the board. I think HVS004 might be the wrong number, can you take a close up photo of the chip (and surrounding circuitry) with a flash for a clearer view?
It's also weird that a bug could have fried itself across a chip that only runs off a few volts. "Bug zappers" usually use at least a few kV. Maybe that IC runs off the 33v line or it was a particularly wet bug, but I suspect that might not be your issue.
