I think some people conflate the LHP with a personal choice to feel like a victim, such that they end up a bit miserable, especially since one can co-create almost any subjective experience, by focusing on it with enough faith and intensity. 
From my POV, embracing the LHP was liberating, in a manner diametrically OPPOSITE to that choice - I posted about that here:
In my own opinion, LHP doesn’t mean “dark” nor RHP “light” - they’re just a choice of personal soul destiny and how you position your goals: "Left-Hand Path," "Right-Hand Path," And Definitions
That’s just my personal opinion though and not something I expect anyone else to adopt.
if you’re not enjoying magick, and being a magician in this glorious 21st century, IMO you’re doing it wrong! 
PS: I’ve always thought E.A. seems pretty healthy, climbing mountains and stuff, and Nate Bales who used to post here was a total beast as far as being muscular, etc. Ref: vitamin D, I neither know nor want to ask exactly who you had in mind (because am not into gossip, nor want to encourage rule-breaking insults, etc) but I have noticed the people in the dareker magick sections of various bookstores tend to look miserable, and like they need a good bath and a workout regimen.
