Here's what I would do differently if I were re-experiencing this from the beginning;
- Take account of any recent changes in your life. The pandemic has been hard on us all so be sure to take into account things you may be subconsciously avoiding or even very minor changes that you may have brushed off.
- Spend some time talking yourself through each change (would be helpful to have another person to do this with but it can be done solo). Figure out your stance on the event. Try to get an understanding of whether you're acknowledging it and its impact on you or if you are trying to purposefully avoid it.
- When you wake up from your 2 hour nap, try to gauge your mental state. This may be hard because you might be still half-asleep but, this is the best time I feel to get truthful responses from your subconscious. By "gauge" I mean to psychoanalyze yourself;
- Did you have a nightmare or a dream?
- Are you feeling exhausted still or are you feeling rested?
- Do you feel any different waking up this time than you do from the last "restful" sleep you had?
- Finally, start a journal for your emotional well-being. It will help you keep track of patterns that may reveal reactions to external stimuli.
I've also had a period of about a year and a half where I could only sleep for about two hours a night. I always had bad sleep habits so I never paid much attention to it.
At the time I had no idea myself that I was worried about any specific issue. I was working out, eating healthily, living a pretty balanced and healthy lifestyle.
It did eventually cause a lot of other issues such as hallucinations (auditory) and some unnecessarily aggressive overreactions.
Now that I've had some time to gather myself and really process what I had been going through. I feel like it was a direct symptom of stress from the prior (not current) president's agendas and my idea of where the country is heading overall.
In addition to the above, I also had some direct stressors from two traumatic triggers from unexpected events in my life.
I think you currently aren't able to sleep for a reason. And if this is a brand new symptom, it may not be immediately impacting your health but slowly you may find your mental state deteriorating.
I'm not trying to scare you, rather I am just trying to stay grounded with perspective of my experience with this.
Good luck, I hope you can figure out what's going on!
