@Bow Oh no no no no I shall never accept an apology for sleepy sleeps!! Teehee only cos I know how hard it is for ya to nod off, and also - SLEEP MUY IMPORTANTE!! So I am glad you got some snoozles 😊
Mm well maybe it's a case of 'the simplest solution is most often correct' - could it literally just be the added stress of knowing/preparing for/enduring your mum being away? Do tell me if it feels like something more or else... but yeah, that is the 'unusual' factor here as far as I can tell. I could be wrong, and definitely wouldn't want to discourage you from exploring all avenues!
In terms of feeling like your supports won't take you seriously - I will say, it is less likely to my mind since it's not a new symptom, it's a ramping up of a known symptom.
Do you pre-empt your disclosures with information about the weight of the disclosure on your mental state? aka something like "I wanna talk a bit about my dissociation, but it's hard because my anxiety tells me you won't take me seriously." I find that priming them to understand that I'm expressing vulnerability will soften the way they respond.
Also, and sorry for spewing clinical stuff at ya, but an increase in dissociation resulting in significant memory gaps like that is also an increase in your level of risk, which any mental health professional worth their salt OUGHT to take very seriously.
I reckon that's a great idea, getting your SW to email! Would that be your one task for the arvo? Cos you also gotta get some rest after all o that!!
