Hi there,
Iam also a 31 yr. old male with similar condition. Started off with extreme insomnia, then anxiety followed by probably depression (dont know first time having it).
I of course have a family doctor keep telling me my tests are fine and referred me to a pyschiatrist!
I personally want to get some extensive tests done too to find the root cause. Please let me know how it goes......!
Sounds like it could be a few things going on there - let us know what the doctor says.
My dad has been going through similar problems and his docs are pretty convinced that he has a rare condition called Pheochromocytoma. This may be something to consider. Good luck with your treatment.
A friend of mine had a lot of the same things and they found sarcoidosis. It's an autoimmune thing and he's been doing great with treatment.
