I was in the industry for 23 years and got harassed out as a 50 year old, which in retrospect, was the greatest "gift" I could have been given. I got seduced by the easy money, perks, and flexible hours...The whole industry is a complete sham, that (as you say) seeks out the easily brainwashed, pliable punching bag types...The Barbies and Kens with their powder puff liberal arts degrees...(I had one of those degrees too!)
Anyway, the job will literally suck your soul out of you, send you into a deep depression and/or existential crisis, and PTSD for many (Especially dealing with the idiotic managers that Pharma seems to breed.) Honestly, just get out...Your sanity ain't worth no stinkin' drug rep job...You will just need to make adjustments and see things in a different light. (And not through the prism of constant comfort and money.)
