I've had anxiety for 14 years but over the last 3 or so I've slowly started having vocalisations of different sorts that I can't control, I've frequently caused people to abruptly turn around to look at me, when I'm so in my head I lack self-awareness and go 'UGH'.

The vocalisations change over time and are too many to remember but the most frequent ones are: 
oh god
ouch Charlie
AHH
Oh heaven and hell
Fuuuck

The ticks or whatever they are come in response to painful, embarrassing or otherwise unwelcome memories and I think it's a result of training myself to push 'negative thoughts' out over the years and they've got to a point they're bursting out of me.

Had anyone else had this? Some of them are funny and I end up laughing at myself after but ideally would like it to stop.

So far I've found dedicating specific time to focusing on the things I'm worried about and fully embracing the negative thoughts to be helpful as well as mindfulness meditation which I've done for years anyway.
