Yes your not alone!!!

Over 8 years ago I was in your same boat....I also found out that the over stimulation was cumulative....So the more noise, movement, light was overwhelming!!

Now to be honest....I always have my sunglasses with me...kinda like a security blanket?
I also anytime around noise and confusion I use noise canceling ear buds...

Most people have no clue other than my inner circle of friends.....

So it does get better....But you will have to learn your own ins and outs....Easy, no.....Possible to find some peace....TOTALY!

Hang in there!
