I say work - I'm volunteering at my local charity shop in the hopes it'll help with my social anxiety. This is going to be a long post; please excuse my venting.
So, the story. I applied with my manly name (now my legal name

). There was no gender box to tick on the application form, but I was hoping the manly name would be enough that they'd assume I was male in advance, and simply think I looked young for my age when they saw me in the flesh.
Nope

I had to talk over the phone before I showed up to the shop, and my voice foiled my plans. They think I'm a girl, and I wasn't brave enough to correct them, so I've been pretending to be one for about a month now. Thought I could keep it up indefinitely, but last shift they sent me home because I was throwing up from anxiety.
I'm going to have to come out. The misgendering isn't the main cause of the anxiety, but it's definitely exacerbating it. And volunteering was partly about getting used to being myself in society, not feeling like an actor in my own life and so on. Doing something as Manly Name for the first time. At least they're getting my name right, I guess

I'll have to speak to my manager over the phone in a couple of days about my rota - I'm going to slot the gender stuff in at the end. Say I'm trans, ask her if she can spread the word about my pronouns. I guess I don't need to say any more than that. I don't know how it'll go down. Again, it's a charity shop - the worst I'm likely to get is passive aggression, and I can always just walk away. I'm not sure precisely why this is making me freak out.
If anyone has any experience to share, any tips on this sort of stuff, I'd be glad to hear it. If not, venting has already improved my mood

also, is there any polite way to correct a colleague/anyone you don't know well on pronouns? That's something I'm currently too awkward to do - some people are so weird about it. Like you're asking them to give you a foot massage or something e-o
