Need help being a good person early today??

on monday, my step-grandmother died(we were not close). she was 87 with alzhiemers, so it came as no surprise. i would have gone over to my step-mother and givin my condolences, but i work 12 hours days, and when im not working, im sleeping. but with my schedule, im off for a week now. so what do i do? my step-mother and i have gotten along only in the last few years(i moved out when i was 15 years old to get away from her). we are still not the best of friends, but i know she loved her mother alot, and i kinda feel bad that she feels bad. there was a dinner thing last night i did not go to( all the family i only see at thanksgiving and christmas for three hours sounds excruciating). but now that every one is gone, ive got no excuses. i have to do something to make her (me?) feel better. what do i do? im the kind of guy that laughs and makes jokes all the time, but im afraid if i try to cheer her up a little, i might say something WAY to messed up.im not very good with feeling and such
