What are the side effects of low blood pressure?

So, I’ve dealt with low blood pressure for years now—I’m pretty much used to those random dizzy spells whenever I stand up too fast or move suddenly—but lately, there’s this other issue cropping up...
I went through a massive period of high stress recently, and now that things have finally settled down, these symptoms have started hitting me.
1. For instance, if I’m just standing there waiting in line at a Starbucks or something, after a few seconds my head starts spinning—not like I’m about to pass out cold, but just a heavy, swaying sensation. Or I’ll be sitting down eating, turn my head too quickly, and boom—instant dizziness. Even when I’m rushing somewhere because I’m worried I won’t make it on time, my head just starts spinning...
2. Then there’s the sleeping. I am oversleeping—like, 12 to 14 hours straight, and honestly, I could probably go longer. It’s not even that I’m exhausted when I hit the pillow; I just drift off immediately, but then getting out of bed feels impossible. Plus, the night terrors have been kicking in, which makes me want to stay under the covers even more.
I don't drink much caffeine—maybe one to three cups a day—and I don't smoke or touch alcohol.
I doubt it’s an iron deficiency since I eat meat almost every single day.
Is this just pure burnout, or could it actually be something more serious?

Hi
A close friend of mine went through a nearly identical situation, and it turned out to be a thyroid issue.
She had those exact same symptoms—dizziness and feeling completely wiped out—but she didn't even require any medical treatment.
Apparently, it was just a minor imbalance triggered by a particularly high-stress period she had been enduring.
The expectation is that once the stress subsides, everything will naturally balance itself back out.
In many cases, people don't even bother seeing a doctor because once the pressure eases up, things just return to normal on their own.🙂
For her, everything cleared up after just a few weeks.
I am certainly no medical expert, but since the descriptions matched so closely, I thought I would reach out.

I honestly think it might be worth getting your heart checked out, just to be safe... I actually dealt with some really similar issues where I felt completely wiped out all the time, and it turned out my heart was the culprit behind all that exhaustion. 😉
Once I finally got things sorted, I felt more rested than I ever did when I first woke up in the morning!

It all comes back to that low blood pressure. As for your sleep issues, you really need to try breaking that cycle by forcing yourself to get up earlier in the morning. It’s purely a matter of habit, and habits can be reshaped gradually if you actually commit to it. Trust me, you'll feel better once you do. You might also be dealing with chronic fatigue. I’d suggest looking closely at your diet—make sure it isn't too repetitive—upping your physical activity, and doing everything in your power to dodge stressful situations. One more thing, though: you should probably have a doctor run some blood work to check your thyroid levels (TSH, T3, T4)...
