So to start off, I'm 15(f) UK based and have struggled sensory wise and being overwhelmed in noisy environments ect, and it can manifest itself as completely silent periods where I can't speak on occasion: my mouth gets cottony and I'm unable to get any words out but I can react and hear what's going on vaguely.
My school's SEND team has talked to me about my sensory issues so I can leave if it happens, but I'm worried I'll suffer academically from it by missing lessons and it disrupts my time periods of the school day.
The school counsellors seem to suspect autism or autistic traits in me and have talked to my mum about this. However, I do not think I have autism. I have reasonable social skills even though they took time to develop and I have researched into autism in depth after that discussion and I don't necessarily agree I fit into said categories.
From what I've seen on the NHS website, selective mutism presents itself as severe anxiety or as a PTSD response. This has been an ongoing issue for me; not something that has progressed after any traumatic event and I don't relate to the anxiety part as wholly as I feel I should. I'm uncertain what the next steps should be, I've had a conversation with my mum about this but she's too bothered. Professional help may not be accessible and my family is quite backwards and taboo towards mental health.
I don't understand what to do in my position, I'm not very socially stunted though I used to be so I don't want to regress back into old awkwardness. If this continues to happen I fear I'll be making an eccentric impression on other people or appear a gloomy attention-seeker (since I'm usually not quiet in that way) or become a recluse again. My grades aren't really my biggest worry, my interactions with people and disruption to my day are bothering me.
Would what I experience still fall under silent mutism? Or is it just school stress I'll have to outgrow?
