I had a rough phone call today at work with someone being rude to the point of mimicking me and asking for "someone smarter" to talk to. I held my own and got through the call, but went home in tears and having all the same thoughts you're having - it's rough out there and I get it being 32 myself, you'd hope you'd find the solution by now. I get laughs all the time bc I answer the phone w blocks at first- it takes a bit to actually answer but I've grown to roll that off me and when the opportunity presents itself, I tell them I have a speech impediment and it shuts them right up. I'm still learning how to cope with it, but I agree w some other posts here, it helps when you're sure of yourself and advocating for yourself when you can - I know that's some I'm continuing to work on
