Hugs to you. I know how you feel.
My heart is breaking. I too am completely alone. I have been experiencing alarming heart symptoms warranting a trip by ambulance to hospital one night a couple of weeks ago. I had a holter monitor on for 24 hours about a week ago and am waiting for the results. And I have no one to tell about it. I don't want to worry my elderly mother or siblings. They live too far away.
I raised a son alone and when he left home to move in with his now fiance two years ago, my world sort of fell apart. I had defined myself as 'mother' and protector, and bread-winner. The lot. I put that boy first in every way and despite a few failings, I was a reasonable mum.
So when he left home I grieved for a few months. I tried studying again, going out a bit more, meeting new people, but still couldn't find a sense of purpose, and fell into deep depression. I was working to pay the mortgage to stay in a big empty house with no one in it, and with memories bouncing off the walls. So I sold it, visualising casual weekly or fortnightly dinners with 'my kids' and random knocks on the door, just the way it always was with my own mum. They seemed happy that I would be nearby.
As it has turned out, I have been here around four months and have seen them maybe three times - when they have needed something. I have asked them round for dinner but they have always had other plans and I feel hurt by the continual rejection, so I have stopped asking.
One time I delivered a tub of icecream and a salad I made to their door (she doesn't cook or eat vegetables). It was evening and the door was open so I called out. No answer. Worried now I called out again. She answered me from the lounge room, where she'd been hiding all along, but didn't come to the door. I was only delivering gifts, not attempting to see them or intrude. He is a chef and I know he appreciates not having to cook when he isn't working! And I know she likes my cooking too.
An hour later my son texted to say thanks for the goodies but could I call before dropping by. This seems a reasonable request but I don't have any idea when he's likely to be home because of his roster, so I am not about to hound him three days in advance to be 'allowed' to drop by with GIFTS. Especially when he doesn't bother to keep in touch with me.
So now I feel a bit silly in my lovely home with a lovely garden in a strange city, all by myself. I think my heart is physically suffering from my son's rejection. And I truly wonder what's left for me.
