ive tried to explain this to people so many times and the best well most successful way ive achieved understanding from other people is to let them know that i only have a certain amount of energy i can give to other people each day and once thats used up i need to be alone to recharge  and if theyve caught me at the end of that energy they might find me more helpful at another time if it can wait  if it cant wait go ahead and tell me what you need but then leave me alone to think through it on my own instead of trying to work things out right that second  emergencies aside this has worked for me  but yeahtotally feel you on this 100
