So I'm at my wits end and it's very unhealthy

Preemptive 'sorry' for the vent!
Setup: I've been at my job for 7+ years and went full-time 3 months ago. There was a month of leave for minor FFS before I came back as me. Prior to that, I had a plan to slowly shift my image over the course of 6 months to lessen the impact to co-workers... y'know, to put enough hints on the table so that even the most non-perceptive and inept could figure out what was going on. This worked well for most; though most just thought I was gay... I didn't mind that at all, however. Some people just had 0 clue lol.
After telling my boss, HR and Civil Rights got involved and I felt pretty good about things... things felt comfy and safe. A mass e-mail was sent out during my leave notifying all staff of my transition, and a directive to address me as my new legal name and to use pronouns. So I arrived to work on day 1 as me and felt wonderful... a new leaf; a new me; a new, more positive supervisor in the mix! A good chunk of my female co-workers were even genuinely happy and excited for me hehe.
Currently: I get misgendered and called my old name by my co-workers daily. It took all of two weeks to basically take that upbeat, new me and grind me down to a pulp, ultimately nearly getting fired due to various circumstances (that's another thread though). When I get misgendered/named, my reaction is always negative and it's really bumming me out. Every day I come into work bracing myself. It's random too... it's not as if it's one or two employees who are just being ->-bleeped-<-s. No one is intentionally doing this, but my Civil Rights rep DID say to me, "you seem to try to see the best in people... do you think it's intentional and you don't even realize it"? I dunno. Not surprisingly though, the VAST majority of incidents are from the males (95% +).
It's not a
complete mystery to me
why this is happening, really. After 7 years, it's like an extended family and that's a good chunk of time to leave behind and adapt to something new. Hey, I get that. I was also quite masculine and a big flirt and my new reality is a bit jarring to people who knew me before (it feels like the common peoples view of transition is that people do this just to sleep with men). What does bother me and is mysterious to me is that it's been 3 months and nothing has changed. Folks have said, "it takes time"... "it's a big adjustment"... "it's so hard"... blah! It always hurts and it always feels like people don't care. If they cared enough, it wouldn't happen; I truly believe that!!
This part sounds ->-bleeped-<-ty, but I could have a better grasp of all this if I was a tall, deep-voiced, husky, unpassable girl. In public, in all types of situations speaking, interacting, just living, I've been misgendered not twice, not once, but zero times. I'm so happy and alive and comfortable and fear nothing outside of work... but I've become so stoic at work due to all of this. Ugh...
The Future: So I write this because I don't know what to do anymore... advice would be awesome!
I kinda want another job because I know for a fact this wouldn't be an issue. If I leave though, it's like I conceded a loss... I shouldn't have to leave MY position due to others faults! Also I don't know how to react. I feel like:
- If I correct people every single time, I fear I'd come across as over-sensitive, picky, and frankly it's not as if I'm telling anyone anything they don't already know. They know exactly what they're 'supposed' to do. It also just feels awkward to correct people, especially in group settings. I don't want to seem like a crazy zealot over the matter.
- If I say nothing and just stay cool as a cucumber, it would make folks feel like it doesn't matter, potentially making it all worse. You're basically giving them the green light to continue it without any repercussions whatsoever. I want it to be like this, honestly. I want it to not hurt when it happens... to not care. Pipe dream on my part, heh.
Look, I don't want to make a big stink of this. Another e-mail from Civil Rights may help, but that'll just draw even MORE attention on the matter and that's the antithesis of what I'd prefer. I don't want fear to be a motivating factor either. Really just feels like it's a situation with no winning solution. I think I'm just screwed, more or less

For any of you who have had similar job experiences... is 3 months too early to adjust? Does it
ever really end, over time? What is the next logical step? What's the best, least drama-ish response to misgenderings by co-workers? Help!!! (and thank you!)
