I'm crying reading this thread (as I'm sure most of us are) and my heart goes out to everyone, the terrible pain they have and do still endure.
I've have pain and grief and difficulties in my life, time does help in my case, the pain doesn't go, but it moves from being at the forefront of everything, until the next thing sent to wound you comes along.
My enormous grief doesn't come from the things I've been through, it comes from the fact I feel utterly alone and I don't have love in my life.
I am single, no children, I've had relationships - but nothing that's lasted or been significant. My family is small and we seem to be getting further and further apart and our contact is in frequent and superficial. I have no parents left. My few friends are lovely, but they have lots of friends and happy families and wonderful children, so I feel very different to them, our lives are poles apart.
I'm doing ok on the outside, I am relatively happy day-to-day when I don't have time to stop and remember that somehow on this planet of over 7 billion people I live alone and spend the vast majority of my time alone.
The ironic thing is I'm a very affectionate and loving person and would do anything to feel and give love to another. I'm NT, so it's not that. I'm bright, funny, and attractive too, which some how causes me more shame being long term lonely - like it must be a moral failing I have which causes me to be alone.
I am very fortunate I have good health so far and am able to provide for myself by working, and I have a sweet dog, but it's like my world is in black and white.
I fake my way through life, putting in a smile and a brave face, but actually it's heart breaking to have nothing to look forward to because everything I do is alone. I don't travel anymore because I don't enjoy that alone etc. Every 'celebration' occasion is stressful, like my birthday or Christmas because I feel I have to really hustle to find people to be with (I actually usually spend Christmas alone now because I'm tired of imposing myself on people).
It makes all the other bumps in the road that life throws at me really hard, if I have a bad day, or a good day I have no one who actually cares.
