Hello Shartyrr
It upset me to read that you feel lonely when you aren't able to watch TV as the sound aggravates your husband's symptoms.
Do you watch programmes on a traditional 'stand in the corner' TV, if so, does it have a hole (not very technical but I don't know the proper name) that you can plug earphones into. Likewise, watching and listening to TV on a laptop / tablet / phone will be easy with earplugs plugged in.
TV can be such a lifesaver, it connects you to the outside world and brings normality / drama / laughter and stress relief to you.
My mum can still cope with company, but I am sure other TP members will have lots of advice on how to plan for family get-togethers with minimal disruption / upset to your husband.
Please don't be lonely, post often and gain strength and insight from others.
