Hi soconfused
I can certainly relate to the dreams and the endless fatigue
It must be terrible for you and made worse still by uncertainty and the unknown.
I don't know if I can really offer any useful advice.
I have been dealing with violent scary dreams all of my life but they were not that bad when I was your age.
Did you suffer some trauma or injury five years ago? You don’t need to tell us but you might need to consider the possible connections.
When I was younger I was on medication that suppressed the dreams and the violent reactions but I learned to anticipate them and suppress them without medication as I got into my teen years. The Longest Sentence
I am over 60 now and in the past decade my dreams have deteriorated significantly and made my life a living hell.
The reason I am telling my story is that I ignored it for a long time but eventually had to go looking for answers because it was destroying my life.
It turns out that I have REM Sleep Behaviour Disorder which involves bad dreams and shouting and actions during sleep. RBD. (Read the comment towards the end of that link)
None of that really helps you but I have been dealing with this for a long time now and have dabbled with almost everything I have access to in an effort to find solutions.
None of the prescription medications I have tried have really helped and most of them made things a lot worse.
Some over the counter medications were useful though, especially Melatonin and occasionally Restavit .
Unwinding and reading before bed can also be helpful for most people.
Alcohol can help me get to sleep but not for long enough to be really worth the consequences or cost although I do find that the occasional nightcap is comforting.
I spend a lot of time during most nights waiting for bad dreams to dissipate before I can go to sleep again without slipping straight back into the same nightmare. I rarely get more than 3 or 4 hours at a time.
I think it would be beneficial for you, in many ways, to seek professional help because where you are now is just as life threatening as any other illness or disease.
You cannot have a happy healthy life if you are not getting enough quality sleep.
It might be possible to get help from online, phone or some other kind of video consultations.
