I lost my ability to string sentences earlier today from being so sleepy. My partner could see I was getting VERY frustrated of it, were kind to me, and understood my gibberish anyway. That stopped me from crying and collapsing.
It is painful to stay awake, and even harder if you are surrounded by people who don't get it and who womt let you nap.
I'm so glad I don't live like that anymore and can rest instead.
