@MsRT I must have missed that earlier in the thread, but I'm so sorry to hear that.
Not the same, but I lost my Grandma this year, and it has hugely impacted the whole experience for me. I had wanted to have children early so she could meet them, and when she passed this year my desire to have kids, which I've had as long as I can remember, vanished. But it was very much in our plans, and the want came back as the grief eased bit by bit.
I've spent the last 4 days overjoyed and happy, but spent at least 2 hours of each crying about how much I miss her and wish I could share this with her.
I don't have any good advice for dealing with it except to totally allow yourself to feel all the feelings, it's okay. You can be happy and gutted at the same time, or just devastated, but don't try and push the feelings down it'll just make it harder to deal with.
We told my fiances family today, and it was wonderful and amazing, but I cried for an hour on the drive home because I couldn't tell my Grandma. That's totally okay, because it really sucks.
I hated platitudes when she passed away, but I truly am sorry for your loss. But you'll be okay, and you can talk to her whenever you want. If it feels to weird to do out loud maybe write her a letter. I have written my Grandma texts since found out. (disconnected number, but it feels like I'm telling her.)
Sorry if this is no use 💙
