Hi s_c, I'm very sad to hear of your loss, and my thoughts and best wishes go out to you.
I lost my sister many years ago when I was 16, she was 20. She was a beautiful, vibrant creative person who made some very silly decisions and paid with her life. Her death was a defining point for me, I was fundamentally altered by it, because I was so young I suppose. I have always tried to help and be honest and real with people going thru similar events, since then.
People respond very differently to being near someone who has lost a loved one; some are great, some are hopelessly insensitive, some simply can't cope with grief in others. You can never tell who will be helpful and who will be hopeless, and some people may really surprise you. I know for me I was amazed to discover that some friends who I thought would be great couldn't handle it, and some others who I under-rated were so open and fearless in their acceptance of the new, altered me.
I don't know why it takes courage to genuinely engage with a person in grief, but it does.
All deaths are different, and some have their own characteristics that can make them incredibly hard to deal with. In my sister's case it was her youth and the terrible out-of-the-blue suddeness of her death that made it so hard to grasp, especially for a 16 year old 'immortal' such as I was...
I can remember being almost admonished, a couple of years later, by a girlfriend who compared her mother's response to the passing of
her mother(of old age) to me and my sister. Apparently, her mother had dealt with it in a very right-on fashion and 'moved on', and I ought to do the same...that relationship didn't last long I can tell you! The age of death does make a difference. At the end of the natural biological cycle is just naturally easier to assimilate. With a young person, you expected to share most of your lifespan together, and there is always a gap where that person would have been.
For you, your sister was young which is very hard, and her death was no fault of her own and is horribly unfair and 'unjust'. And also not an easy death. You got to say goodbye, which is a great gift, but also must be terribly difficult. I can only imagine. She sounds like a wonderful person, and the things she said to you must be comforting. But that doesn't change the hard fact that she isn't around anymore and you go on thru your life without her. Outcast searcher is right to say that the passage of time does ease this pain. It's strange to me that this is so, but it truly is.
I also found talking to strangers very helpful in the months after my sister's death. Other people who had been thru similar events, but who I didn't know. I'm not sure why this was, many reasons I guess. There is something freeing about the person you are talking to not having any expectations of you, and also of them really understanding what you are going thru. Quite soon after my sister's death, I started to get the feeling, rightly or wrongly, that people were looking at me for signs of whether I had 'got over it' yet. Talking with people I didn't know allowed me to express myself without this feeling. A really great therapist (just a wise old man really) helped a little too, for much the same reasons- compassion and insight without expectation or judgement. Also, talking to strangers meant that they would ask me what my sister was like- and I would get to tell them all about how amazing she was, which I loved, and found comforting.
A film I found comforting was called
Fierce Grace. I saw this many years after the loss of my sister but nonetheless it touched me. It's about Ram Dass after he suffered a massive stroke, and despite my atheist scepticism I found it tremendously moving. It is essentially about loss, and the parts that deal directly with death are powerful indeed. If you ever watch it, you could fast forward thru the history/backstory if you need to, altho it is a pretty classic documentary of another time, too.
Strength to you,
all the best yb
