As a mother of a non-verbal son with autism , I often hear people telling me: " You are an angel " or " I don't know how you do it " or "I don't know what would I do if I were you??!", etc. I have to admit that I feel very uncomfortable hearing that because caring for my son is the most natural thing that comes to mind and yes it is very challenging and difficult at times, but my answer to all...and to the question of "how I do it?" is I get up every morning and DECIDE that I have to do it. I put one foot in front of the other and go, and I would assume that every one can do that if they DECIDE to do it as well regardless of the circumstances because to me it is not just an obligation but it is an honor and a privilege that I am entrusted to care for someone so vulnerable like my son, and as someone once said "the measure of a civilization is how it treats its weakest members.".
