Things that cause me stress:
IEP meetings, lack of education among school staff, balancing needs of siblings, dealing with irritability from ASD child when I am also feeling irritable, health insurance/health care costs, being able to find appropriate child care during non-school hours, having to take extra time off work for meetings and appointments or when said appropriate child care is not available, him hurting himself when he bolts from overwhelming situations at school, him not having friends, not getting enough sleep because at 7 yo he still always wants to sleep in our bed, misunderstandings, always needing to anticipate, plan ahead and generally be "on" all the time to avoid unexpected changes which will cause meltdown, when "the toy" that is the most important thing in the world at the moment gets lost or misplaced, not being able to move on to the next thing until; "the correct" lego piece is located and properly placed the new book is finished, the TV show is over...
Some of the things that relieve that stress:
His hugs, him telling me I am the best mom EVER, seeing his enjoyment in the things he creates like paintings, comic books, lego creations, paper airplanes, watching when he and his brother are playing wonderfully together, his unique perspective on the world, his enthusiasm for the things and people he loves, his honesty, seeing how he can make total strangers crack HUGE smiles (and not the laughing at him kind of smile but a genuine that-made-my-day kind of smile)...
