Sensory Overload

Hello, 

I do not yet have a diagnosis, so I'm not sure if it's ok to post on here. Please let me know if it's not and I'll remove my message.

I had my ASD assessment 3 weeks ago, and I'm awaiting the report, but things seem to be getting more and more unmanageable. Sensory overload in particular, especially noise. I just wondered if anybody may have some advice please? I wear ear plugs all the time and sometimes defenders too. But I find myself so worn out all the time for so much sensory input, leading to meltdowns and leaving very little if anything to give. I have recently moved house and so anxiety is definitely alot worse at the moment, could things being more heightened be linked with stress in some way? Forgive me if this is an obvious question. 

Thank you
