(((Big hug)))) I know this bubble you speak of (shock). I spent the first 4 months in it, and I still find myself there from time to time.
I have managed to start using past tense. It took a little while, because it was natural. You can't change something you have been doing all of your life over night. But, I need to eventually do it. That's what it is, but it all feels incredibly strange. It all seems like one big blur. I don't know how 7 months have gone by already.
I had plenty of people reach out. Family was beating down the door as my dads body was being removed. They did not stop. My friends called and asked to come to the graveside service, told me they would be there, and did not. I guess, no matter what, it's all going to seem backwards. I had so many people around when I needed a moment to myself *don't get me wrong, they helped, more than I understood then* and no one around who I really needed and felt more comfortable falling apart around. My mom on the other hand, had everyone she needed, which was great. That's the only thing that stopped me from screaming, "GTFO"!! :-/ I'm not going to blame anyone. I think about and stop myself. It's misplaced anger, I know it, but that does not stop you from feeling it. I just need some time to get past it. And at this point I honestly have no idea what to say. None of my closest friends have lost a parent so they won't understand my crazy
I am thankful for that.
As others said, it is going to take time. You have to keep on keeping on, and talk to people who get it when needed. Things will get better. I'm not sure when, but I know they will.
