How interesting. I am learning about my Bipolar I disorder and hadn't heard about this one. It's so true, but I am OK with lots of noise that drowns itself out. If there are certain noises that stand out, or are loud and repetitive, then I just can't take it. I need to leave the area. It drives me bats and I get VERY irritable to the point where I've confronted people in a semi-aggressive manner. Not good. But with the meds I can tolerate a little more.
I've always always had an extremely heightened sense of smell. I can't do candle shops or those body/bath stores. It gets to me on a strange internal level. I can't concentrate. It's just too much. On the flip side, I can walk into someone's house and tell them within 2 minutes if one their pets has urinated on the carpet and exactly where. If it's multiple locations it takes me longer. Certain animals' urine has a strange woody/sweet smell. Don't judge.

It just smells that way to me. People tell me it's not supposed to smell that way.
