Has anybody ever had shingles'. If so, how severe was it and how long did it last?

My brother and his wife died, and I helped my bother when he was dying. Afterward, I developed Sciatica after being our running. (I see that Labron James has it) Now with all this stress, I have developed terrible Shingles, and my doctor said the continued stress has lowered my immune system, and that has allowed the Shingles to develop. Anyone have this happen?
