My dad just hit 85 years old. He lives close to one of my brothers. He's got medical problems and the docs warned my brother a few times already that 'this last problem' could very well be one that there was nothing they
could do to save him. That started about 10 years ago.
My dad hears what he's told and figures that's THEIR opinion, and since it's a one-way opinion, he ain't gonna prove 'em right.
He watches the medications they give him, some of which he finds-out they shouldn't have prescribed by his reations, and meticulously maintains his body like it was a prized delicate machine.
He's determined to get as much mileage out of that machine as God grants him.
I'm a tech like you. I don't know as much as you, but I know that I've NEVER found an instrument I couldn't repair. Sure some were too expensive to repair, so I didn't. But I knew what was needed to fix it.
Did you ever let an instrument beat you? Did you ever find one that was just too much of a problem that you couldn't figure-out because it was beyond you?
I doubt it.
You're waking around in a machine right now that's got multiple issues. It needs maintenance, not a trip to the trash bin. Are you going to let it beat you?
I'm no doctor, but this is the first thing that comes to mind about your situation:
My dad has to take a dozen or more pills for different things every day. There have been times when I thought he was suffering from dementia, and it turned-out to be the pills he was on, and they needed to be
swapped for a different prescription. I've seen depression, that also turned-out to be due to medications, that needed to be changed.
Is it possible that pills you're on might need to be changed for physical or mental/emotional acuity?
Are any of these doctors looking at the pills you're on to see if there are any undesireable side-effects, or complications from interaction with one another?
Are one or more of the pills themselves, CAUSING physical reactions that are complicating your symptoms?
I know what happened when they brought the extra doctors in to re-evaluate your condition. They went with what the origianl doctor diagnosed, not wanting to ruffle feathers.
My oldest boy was diagnosed with allergies when he was a child. I kept going back to the same doctor office but would occasionally get different doctors because the original doctor would have the day off.
ALL of them kept just reinforcing the original doctor diagnosis, telling me to just keep giving my boy the allergy medicine and wait. None of them seriously considered checking any alternative.
When the boy became so lathargic that he didn't even respond to me anymore it scared the hell out of me.
I fought back and went to a completely different doctor office. That doc checked the boy. He didn't have allergies, he had pneumonia.
I know you've got heart and other issues that are valid. The docs you saw ran tests and said they can find nothing wrong.
Maybe one of your meds is causing reactions in your body, and needs to be replaced with something different.
I'll tell you right now the difference I see in your post, compared to my dad's attitude.
He doesn't even consider 'giving-up'. It's not an option that even enteres his mind. You need to get it out of yours.
Life is slapping you down right now. You gonna provide needed maintenance to your equipment, or let it slide?
ATTITUDE is what makes a good tech. Not letting problems kick your butt.
You need an attitude adjustment right now, find somebody who'll provide it.
Do you go to church? Anybody there you can talk to?
Don't give up on the search for solutions to your physical symptoms, but change your attitude about being determined to do something about it.
All of my married aunts and uncles died within a year of one another. One died and the other one didn't have any medical issues, they just gave up after losing their spouses.
If you don't buck-up for this fight, attitude will do more damage than any physical issues that are bringing you down.
You get one shot at life. This is it. Hold onto it until the Big Man upstairs says otherwise, ... not you.
