So moved to tears by this thread.
I'm very very fortunate to have a few:
The friend who was early stages of pregnancy herself and with an older dc with special needs when I was having my 2nd mc insisted my then dh bring her to hospital to see me. I hadn't known her long and I was so touched and said to her I'd have understood in the circumstances (she'd previously mc herself) if she'd felt unable to come. She told me not to be so daft and she visited every day and even managed to make me smile at times.
The man in London who seeing I was dealing with a very large broken suitcase (wheels had literally come off) while I was moving having been thrown out of previous place and I was at end of my tether went out of his way to help me on and off the tube twice until could get a taxi to my final destination. I was young and foolish and initially wary as he had a purple Mohican and many piercings and tattoos which at first made me feel intimidated.
A friend from uni (who I barely knew at that point) when I had my breakdown and was literally going out of my mind with anxiety one night, had no support network locally at that point who drove over, and just sat with me. A simple thing but so so kind, just sat with me talking, distracting me. They literally saved my life that night as I fear what I would have done without that support.
My best friend who'd a few months earlier moved away for work, my ex was playing silly buggers. We were living opposite ends of the country at that point and my ex in a 3rd location. He was threatening not to return dd after a contact visit, it was a bank holiday weekend so I couldn't get hold of my lawyer, and I was scared. Ex wasn't even letting me talk to dd on phone. Bff showed up at his (a 6 hour drive from her place) without even telling me, took my hand and said "come on let's go get dd" I think if I'd not had another adult with me ex would have tried to keep dd.
I am and always will be so very grateful for those kindnesses and hope that what I've done for others is also remembered fondly and I hope in the future to be able to do more kindnesses for others because my mh is once again very bad and I'm feeling pretty useless at the moment.
It's lovely to be able to help people and I miss that.
