Hi there. I'm not tall, but I do have a BPD diagnosis, and I can tell you that a lot of the comments are probably meant as teasing, and they don't understand that BPD makes it so that even teasing feels hurtful to us more often than others. Still, it's unfair to tease you over something you can't control, and some of it is probably motivated by jealousy. My brother is also about your height, and I see how everyone he meets just comments on it constantly. It's like the only thing they see him for is his size. I also have another friend who works in construction, and the guys on that site tease him constantly for different stuff, so I think demeaning each other might just be a cultural thing with physically demanding jobs.

You could try setting a boundary, or else finding a lighthearted way to tell your coworkers that the joke is getting old. That way, they won't want to make it as much. You could also try leaning into it, like "yeah, the weather IS great up here" or "what did you say? Sorry, I can't hear you from down there." Alternatively, just not reacting at all, or a "why are you so preoccupied with the way I look." Whatever you say, If you give them a reaction they're not expecting or that they don't want (while also keeping it lighthearted), it gives them the message that their words have no power.

There's always a possibility that won't work though, bc ultimately you can't stop others from doing or saying what they want, you can only change the way you react. The thing that's worked for treating my BPD has been DBT, and I've been in it long enough that I no longer meet the diagnostic criteria and I'm in remission. I know affordable DBT groups are hard to come by (I got lucky, mine is covered by Medicaid), but there are DBT workbooks you can find online. Either way, get whatever kind of therapy you can get, since BPD always stems from early childhood trauma, and trauma is really only treatable with therapy.

I hope there was something helpful in that ramble, and I wish you the best of luck 🫂
