The fallen Forum Confused on how to ask for hel..

On October 15th 2012 i lost my grandfather and i sat by his side with my family and couldnt get my feet to move when his heart rate started to dissipate so i took the hand of my aunt and held it so tight...And watch him take his last breath.... I have been told that i should have walked out on him while he was passing and i could be handling his loss better but since i didnt leave the room people tell me that it was a bad idea and thats why i am still having a rough time dealing with his passing.... It has almost been a year and i still feel as bad today as i did the day i lost him... He was my first lost in the family so maybe thats why im stuck in this rut... But the only person that i want to spend time with is my grandmother and my aunt and be back at my grandfathers house so i spend as much time as i can away from my family and at his house because being there i feel like i can breath and be my self unlike i feel at my own home... I have been debeating on how to tell my mother that i need to see a doctor because even though it was her father that we lost i think i am taking it harder then she is... I have distanced myself away from everyone that i know except my grandmother and aunt.... I guess  what i am trying to ask.... is there an easier way to get someones attention dealing with depression then sitting them down and getting them to get me the help i need?
