>Start new job over a year ago
>Find out on the first day that they're going to change the duties I sign up for, and give me TWO supervisors
>First supervisor is chill as fuck, never have any problems (this was supposed to be supervisor I was assigned to in the first place)
>Second supervisor is the epitome of a dick
>He's also a 25 year old 5'5 dyel manlet
>Talks down to me
>Constantly implies I'm a retard no matter what I do
>Pretty much shatters any confidence I have the moment I walk into his office
>Tired of constant bitch mode around him so I start lifting to vent frustrations
>Year later, I've made really good gains, don't look like a dyel fag anymore
>Confidence surge around women in the office
>Get a lot of respect from coworkers and even my first (original) supervisor
>Still go into the second supervisor's ffice
>Immediately go into stuttering autismo bitch mode
>mfw no matter how big I get I'll always feel like a manlet bitch in his office

What gives /fit/? How do I build up my confidence in this scenario? It's not like I'm even fucking up at work either, I do a damn good job at what I do. It's just that this particular guy gets off on being a dick, and I can't help but turn into a spaghetti monster in his office.
