@rangerr having a disorder doesn’t mean you’re broken, ruined, or bad. It just means that some biological mechanism is different/malfunctioning. 9.5 million in the US are diagnosed with General Anxiety disorder and there are many other Anxiety disorders out there (such as Social Anxiety Disorder, and Agoraphobia, etc.); it’s very common—especially among women. Then there’s the thyroid possibility, which is quite common as well. The point is that being perfect is the exception rather than the rule, and being less than perfect doesn’t somehow mean you’re broken (we’ve all got something we’re dealing with).
As I understand it, a disability is something that interferes with your ability to function in day-to-day activities. What you’ve described seems to qualify. Honestly, an anxiety disorder or a thyroid problem would likely be good news if it were causing your insomnia, because they tend to have good treatments available with fairly high success rates. Some of the other causes of insomnia are much harder to diagnose/treat and can have much poorer outcomes.
Honestly, you don’t get badass points for not going to the doctor when you’re not feeling well and “toughing it out.” I’m guilty of this myself, but many people die every year from this attitude (not that you have a fatal condition). The point is that the attitude of not going to the doctor when something is wrong is itself, dangerous and unhealthy. The best friend of a guy I know died last year from pneumonia because he was too stubborn to go see a doctor for his cough because he was “tough.” He would still be alive if he’d gone in even a couple hours before he died (I think he was in his 30’s and healthy in every other way).
My best friend recently got prescribed a mild dose of anti-anexiety pills and he said he’s never felt better. Other than him being a generally neat and tidy person, I would never have known that he had anxiety issues (he certainly wasn’t a “don’t step on the cracks” or count-down-backwards-from-ten before turning on the lights ODC person, nor was he a germaphobe or anything like that). I certainly wouldn’t have ever described him as “broken” in the 10+ years I’ve known him.
Only a doctor can diagnose you, and they’re going to have an easier time figuring out what’s wrong if the problem is still occurring. I would suggest you go sooner rather than later, so you don’t have to keep suffering like you’ve been. I would try to keep a log-book/journal of when you wake, go to sleep, what you ate, any caffeine or other stimulants/depressants you consume. I would also record any exercise as well as write down any anxious feelings that may occur to you during the day. The more data you can record, the better in terms of getting to the bottom of this.
I’m glad you finally got some sleep, but it’s pretty clear that you’re not feeling normal, and that should be enough motivation to schedule an appointment (I bet Boba Fett would make an appointment—because it’s the smart thing to do, and he’s a crafty fellow). Best of luck with whatever you decide to do, I hope you feel better soon.
Just one other additional point to mention. Having a psychological disorder isn’t a character flaw. It doesn’t mean that you’re weak-willed, or lazy, or whatever. Most of these things are caused by neurotransmitters which you have no control over.
