Is it normal to feel guilty when you lose someone?

Just this morning i got a big shock that someone in my extended family just passes away. Now, you see your family everyday and know what's going on in their lives; but when it comes to your extended family, its a little tricky. You meet them once or twice a year on occasion but still every person holds a special place in your heart. Now the person about whom i'm talking about lives quite close to my house but still because of daily routine i'm unable to see her. A woman in her 80's she always gave me blessings and wanted me to progress and continue to be the person i am. Something fantastic just happened to me and i was supposed to meet her in the next couple of days to let her know the good news. But as fate would have it, it didn't happen. I had not met her for the last 3 years even though she lived just 20 min away from my house and now i don't know how to get myself out of this guilt that i should have met her when there was time. Really this has taught me quite an important lesson about loving people around you and cherishing life in totality. It would be a great help if you could help me get through this time and help me feel better.............
