My condolences to you and yours, Black cat.
I am now dealing with the aftermath of mom's passing and can relate to some extent to your feeling so alone. I wish you strength at this time. There is so much to do and at times it feels like it will never all get done.
I keep reminding myself to take things one step at a time. The past few months it has felt very much like all I have been doing is looking down as I put one foot in front of the other, but you know what? I am seeing light at the end of the tunnel. So if nothing else, I hope I can offer you some comfort in knowing that you will get through this and the stress will slowly come to an end and you will be able to mourn your mother and honour her by living the best life you can.
Best Wishes,
JD
