Hard job: To the extent that grey hair start is due to stress and the difficulty of a job, obama has the toughest job on the planet. This may have contributed to his seemingly premature or rapid onset greyness.

Stress Depigmentatio: Stress can lead to earlier depigmentation of hair that is already genetically predisposed to graying. However, in general, hair loss is more associated with stress than hair graying.

What does it mean if the ultrasound did not see anything in the sac?

Blighted ovum.: That would depend on how advanced the pregnancy is. By 5 weeks there should be at least a yolk sac present in the gestational sac in the uterus. By six weeks a fetal pole should be seen and 85 to 90% of the time a fetal heart beat is noted by six weeks. If there is no fetal pole or yolk sac present by six weeks, it is unlikely that the pregnancy is normal. That is referred to as a blighted ovum.

Get Evaluated: After reading your listed questions, i gather you are having some difficulty in making decisions, not being able to finish assigned tasks or get organized, and maybe not realizing that psychiatry medicine is not the same as behavioral psychology. Unless you are already attending med school or planning to do so. Anyway, i recommend you get tested for adult add, complete physical and lab work.
