The problem with having an invisible illness is that sometimes you need a little help; however, you don't appear to be someone who needs any help.
The problem with looking like you do not require assistance is that it makes it harder to ask for that much-needed help. After all, you appear perfectly capable of doing things the same as your peers. There lies the rub, you know you aren't the same as your peers still, you pretend and lie to yourself at times. At least that's my issue.
I lack the grace to ask for assistance when I need it. Instead, I struggle, wasting energy and increasing my pain while trying to keep up with my peers. Even worse than my inability to ask for help is my utter incompetence in accepting proffered help.
There is no shame in requiring aid. Help is not a sign of weakness, either in the asking or accepting of it. Being stubborn, to the point of your detriment, is a problem. It is one of my hardest struggles with having an invisible illness, and it is a needless one.
