I'm so sorry about all those losses, especially since you don't seem to have a lot of support right now.
I'm now 65 and have only one uncle left on my mom's side (out of 13 children) and only 3 of eight children left on my dad's side. And I've lost a bunch of dear friends--that comes with age, alas. But I gather you are younger. It's hard to lose all those folks at a younger age, I find making new friends and "relatives" keeps me going.
We are here for you, too.
