i need help maybe

i'm always searching for reasons why i act the way i do or why my thought process is so nonsensical- is that an oxymoron, a nonsensical thought process? i guess, and i'm a person to guess and think and feel like a lot, that a single event cant be attributed to my irrational behavior. but...its just so frustrating. more and more i'm recognizing how my mind doesn't seem to work like normal, for example, the way i piece things together, or more specifically, i'll want to know why something is happening, and i'll ask when. i dont know. but its just become increasingly annoying because i never get the answer i want, a typical conversation using that example:
"when are we going to john's?"
"i don't know, around 6?"
"what?"
"...."
"no i meant why are we going there?"
"but thats not what you asked.."
"i know but..thats what i meant to ask.."
just another unnecessarily awkward situation brought to you by the letter N, for erin's nonexistent brain.
