G'day la doctora,
My opinion, would be to get a recommendation from your family GP to see a psych.
I would think to have a professional rule out whats is and what's not would be a welcomed relief for you rather than come up with three conditions that come to mind...(hopefully, that hasn't come across in a rude manner
)
I have a different career path than you but relate to "never going to be what I wanted" which I accept and do the best that I can, rather than look to the future when I'm in the now.
Nice to talk to you
