You asked for bluntness so....here's some terse writing for impact, not nuance.

You buck the hell up and stop sounding like some teenager who has just entered the workforce, you stop spending time making up fake narratives in your head about what people might think about you ('lowly coder'), you stop painting individual humans with one big brush based on their job titles, you stop doing the same thing each time and wondering why you get the same results regarding credit and communicating your ideas/value, you understand that it's a job and in most cases there will always be someone telling you want to do, you accept that large companies with more money involves tradeoffs and you either accept them or you don't, you stop looking for 'glory' at work.
